LumiDriver Posted November 14, 2007 Report Share Posted November 14, 2007 Hey all, as you have read in previous posts, my coolant is disappearing into my exhaust, the engine is overheating, and there is a new WP, Thermostat and no puddles under the car. It died today, multiple times. I wasn't able to get very far. It would start extremely harsh, and it was bad. My girlfriend was there too, she knows nothing about cars, and she thought it sounded bad. SO, after a lot of googling and reading here on the forums, I think I've narrowed it down to the LIM. Which is a pain from what I've heard, but cheaper than anything else serious. I was browsing on autozone to find the price of these gaskets, and I think I found the, but I need to know for sure. LIM Gasket If those are the right ones, awesome! Anyway, I was looking for a complete and thorough walkthrough for replacing these. I'm very insecure about doing things without good instructions, but I can't afford for someone else to do it. Please help me, this is the last resort, because I plan on selling the car if the gaskets fix it, and getting a 1998 Dodge that has full backing of my parents if it breaks. Thanks! My email address is vipersfate@comcast.net if you have something to add! Thanks so much in advance! Quote Link to comment Share on other sites More sharing options...

GutlessSupreme Posted November 14, 2007 Report Share Posted November 14, 2007 I haven't read your previous posts, but... have you checked your oil to make sure it's not frothy milk? You say coolant is dissapearing into the exhaust.. I guess that could be the LIM, but it sounds more like head gaskets to me. Quote Link to comment Share on other sites More sharing options...
LumiDriver Posted November 14, 2007 Author Report Share Posted November 14, 2007 It is frothy milk . I was reading that walkthrough, and a few of those things I do not know what some of these things are. Remove the upper intake manifold. Refer to Upper Intake Manifold Replacement . How would I got about doing this part? Remove the fuel feed and return pipe from the manifold. Refer to Engine Controls. What are those? Remove the fuel injector rail. Refer to Engine Controls. How do I do this? (Sorry, I've never done that before) Remove the power steering pump pulley. Refer to Power Steering Gear and Pump.Remove the power steering pump bolts. Move the power steering pump aside. Refer to Power Steering Gear and Pump. I haven't done that either Disconnect the heater inlet pipe from the manifold. Where is that? Disconnect the straps from the heater outlet pipe and ignition wiring harness. What are the straps? Remove the valve rocker arm cover. Refer to Valve Rocker Arm Cover Replacement . How is that done? Remove the bolts. What bolts? lol If I can get those answered, I think the reverse will be easy. Thanks! Quote Link to comment Share on other sites More sharing options...
chadz34 Posted November 14, 2007 Report Share Posted November 14, 2007 The upper intake manifold is the ''plenum'' you should be able to remove it by removing the six bolts on it. You will need to remove the throttle and kickdown cables. The fuel feed line goes into the injector rail, it should be easy to remove. I think you can skip the steps for removal of P/S components. The gasket you are trying to repair is under the fuel rail....which is another six bolts...you WILL need to drain some of the engine coolant (plug on bottom of rad) and that will avoid coolant spillage. The injector rail comes out and the gasket is underneath it. Makes sure you Clean the surface in whichjh the new gasket is to be applied. HJope that helps.

Thanks! Step slowly away from the car and tow to a shop... Seriously, all those should be common sense for a person that has sufficient mechanical aptitude to do such a job. How is it done, look!!! If it won't come right off, then remove whatever is keeping it on Quote Link to comment Share on other sites More sharing options...

LumiDriver Posted November 14, 2007 Author Report Share Posted November 14, 2007 It's not that I don't know what I'm doing, I just want to make sure that I can do this well. I hate doing half assed jobs. So it does sound like an LIM problem? My boss is saying that it could be a head gasket. Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted November 14, 2007 Report Share Posted November 14, 2007 The hardest part about doing LIM gaskets is torquing the bolts correctly.. and if you know how to do that, its an easy job.. just takes a while. Why dont you just go the headgaskets while you already there? I mean 16bolts you need to take out, clean up the block and heads, then torque down 16bolts.. its not that much more work. If you cant figure out what one it is, just do all of it. Quote Link to comment Share on other sites More sharing options...
R Dubya Posted November 14, 2007 Report Share Posted November 14, 2007 if you aren't 100% positive that the head gaskets are not blown, or one cylinders crush ring hasn't failed, then you will be doing yourself a grave injustice if you don't at least do a compression test to diagnose. Even if you have even compressions it doesn't mean the gaskets are still good. The only 100% way to know is to remove the heads and see with your own eyes. Besides, in all it will only cost about $250 more including parts and planing of the heads to ensure flatness. And that's if you decide to do the valve seals, which isn't entirely necessary. I recently did a 97 3400 (same design) and the compression revealed nothing, cylinder one's crush ring was separated and I would have had to do it twice had I not had the notion to just do it anyway. You are that far, just do it right, that way you don't want to hang yourself when its still burning coolant. Quote Link to comment Share on other sites More sharing options...
LumiDriver Posted November 14, 2007 Author Report Share Posted November 14, 2007 The problem on that is (I would do it too) is that I don't have that money. I have 0 dollars to my name, and at the end of the day I'll have 64 dollars. Quote Link to comment Share on other sites More sharing options...
R Dubya Posted November 14, 2007 Report Share Posted November 14, 2007 well its going to cost more than $64 for the gaskets, oil, coolant, silicone sealant, bandaids and neosporin, pb blaster, etc etc. I'd put a large bad of doritos against your headgaskets being bad. if you don't do it the first time theres a good chance you will do it all over again, plus extra for the head set and everything else. all in all I would expect to spend at least 12 hours leaning over that car if you've never done it before. But hey man, to each his own, good luck, and we'll all be here to help you out if you need it. Quote Link to comment Share on other sites More sharing options...
LumiDriver Posted November 14, 2007 Author Report Share Posted November 14, 2007 I've done this before, but not on a 60*V6 before.

chadz34 Posted November 14, 2007 Report Share Posted November 14, 2007 I've done this before, but not on a 60*V6 before. My parents aren't even caring that this is happening, and they don't even want to help me. It fucking sucks. Man, it had been said earlier, it's all of 16 bolts dude. The fuel injector rail has to come off thats it, it's a PITA, but I wouldnt pay anyone to do that...just be happy you don't have a DOHC. I leanred most of what I knowonce I bought a Lumina. If you are questioning those basic instructions, even the paragraph I wrote myself haha....buy a BMX bike or something with the 60 bucks Quote Link to comment Share on other sites More sharing options...

LumiDriver Posted November 14, 2007 Author Report Share Posted November 14, 2007 Yeah, it's just pretty hard because of th emoney problems right now. Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted November 14, 2007 Report Share Posted November 14, 2007 Then save your money and fix it when you can afford to. Park the car right now and use something else. if you dont youll have bigger problems that will cost more than the $120ish fpr all the gaskets you need.

LumiDriver Posted November 14, 2007 Author Report Share Posted November 14, 2007 Normally, that would be fine. I don't have anything else. Normally I would have my mom's Eclipse, but the suburban's rear end died, so my step dad needs the car. I just got off the phone with my mom, and she is thinking about letting me pay her back for the gaskets and items that I need. I told her that I need head gaskets too.

LumiDriver Posted November 14, 2007 Author Report Share Posted November 14, 2007 Ok, so 2 head gaskets, LIM gaskets, Coolant, silicone, intake plenum? what else will I need? Quote Link to comment Share on other sites More sharing options...
BXX Posted November 14, 2007 Report Share Posted November 14, 2007 Ok, so 2 head gaskets, LIM gaskets, Coolant, silicone, intake plenum? what else will I need? You will need a complete headgasket set and head bolts. coolant, oil and filters for 2 changes, silicone, torque wrench, probibly some engine flush, a new thermostat, a bunch of brake parts cleaner to clean all the gunk off the parts, a good tool set, breaker bar, and of course a good machine shop to check out the heads. I think that's about it... Hell, I've changed LIM/Head gaskets soooooo many times on 3100s Oh, and a good prey that your bottom end hasn't been washed by the coolant... Sometimes you get lucky and they are perfect, other times, they can be wiped in a few seconds... You do have a second option however, getting a junkyard engine. Most of them have already prollly had all this work done already and can be had very cheap. Quote Link to comment Share on other sites More sharing options...
LumiDriver Posted November 14, 2007 Author Report Share Posted November 14, 2007 Headgasket set? The 180$ ones? Why new bolts? Quote Link to comment Share on other sites More sharing options...
Regal_GS_1989 Posted November 14, 2007 Report Share Posted November 14, 2007 Headgasket set? The 180$ ones? Why new bolts? The Bolts are torque to yield. Meaning that they stretch once they are torqued down. Personally i wouldn't trust re-using head bolts. (At least on these engines) And if the car has been run long enough with coolant in the oil, then i'd be a little worried about spending the time and money on replacing parts and then wiping out the bottom end because the coolant made it into the bearings.

LumiDriver Posted November 14, 2007 Author Report Share Posted November 14, 2007 When I pull the dipstick, it doesn't have coolant smell or look to it. It's on the oil cap that I see the foamy. good point about the bolts. Thanks for letting me know that. Quote Link to comment Share on other sites More sharing options...
