f_399 Posted January 3, 2006 Report Posted January 3, 2006 Where can i find a good writeup on replacing the intake and head gaskets that commonly fail on the 3100? Quote
Supreme Cutlass Posted January 3, 2006 Report Posted January 3, 2006 I'd just buy a used dealership service manual Quote
SigEpCutlass Posted January 3, 2006 Report Posted January 3, 2006 i'll look tonight at my Haynes manual to see if that's any good. If it looks good, I'll digitally scan it in the coper @ work tomorrow for you if you'd like. Just let me know. Quote
THe_DeTAiL3R Posted January 3, 2006 Report Posted January 3, 2006 Haynes manual has a decent writeup on doing the LIM gaskets. Headgaskets aren't a common problem with the 3100s.... Basically just drain the coolant, tilt the engine, unbolt the coil pack/alternator/PS pump, remove front plug wires (rear can stay), take off some coolant hoses and stuff. Pretty straightforward just time consuming. Should be 10ft/lb torque spec for the lower intake bolts if you buy the GM ones. You will need a torque wrench as far as "special" tools go, the rest just hand tools. Quote
SigEpCutlass Posted January 4, 2006 Report Posted January 4, 2006 I agree with Dave after reading it last night, but he'd know better than I would. Ya know since he's sorta done it. Sorry, I forgot the fucking book in my room today...let me know if you want it scanned. Quote
f_399 Posted January 4, 2006 Author Report Posted January 4, 2006 ill let you know a guy from another forum is coming this weekend to fix my car i think he has done it before what parts would i need to replace the head and intake gaskets? anything else i should replace since i am already there?

Oil Pump Drive O-Ring. http://www.w-body.com/forum/viewtopic.php?t=16325 I read through that and kinda scratched my head maybe it's different engine? Anyways see the round thing at the bottem of the pic (has coolant on it) remove that 1 bolt to take the top piece off, then pull the sucker UP. It's kinda big so it takes a little bit of effort. You'll probably need an adjustable wrench to tug it out. Quote
Crazy K Posted January 4, 2006 Report Posted January 4, 2006 Basically, it is the same on all the engines. 2.8, 3.1, 3100... 3.4 (head interferes! fun!) Quote
SigEpCutlass Posted January 5, 2006 Report Posted January 5, 2006 Do you need me to scan my Haynes manual for you at work tomorrow? Please let me know and I'll take it to work. Quote

Crazy K Posted January 6, 2006 Report Posted January 6, 2006 yeah a guy offered to do it i might still end up selling it after its fixed NOOOOOO! once it's fixed you should be home free! Quote
DiscoStudd Posted January 6, 2006 Report Posted January 6, 2006 So who are you having fix it for you? Lemme guess, cutlsp? Quote
f_399 Posted January 9, 2006 Author Report Posted January 9, 2006 yup its you! man i got all excited when we decided to put the engine back together... i thought i would have a car this week! damn felpros didnt fit! Quote
f_399 Posted January 9, 2006 Author Report Posted January 9, 2006 it was the right ones but somehow it would not fit..... went to oreilly and autozone 96mcls can better explain, he will be getting gaskets from gm and he will install it this coming weekend Quote
jeremy Posted January 9, 2006 Report Posted January 9, 2006 well at least the person working on it was smart enough not to half-ass the repair... Quote
GP1138 Posted January 9, 2006 Report Posted January 9, 2006 That's why I didn't want to get Fel-Pro. I got GM just because I knew I could trust it. Quote
96mcls Posted January 9, 2006 Report Posted January 9, 2006 one of the little dowel pin things were too fat. i could only get it to go like half way in, and i really didn't want to press to hard and break the plastic. we tried scraping a little off with a razor blade, but having a razor that close to a already problematic gasket was just asking for trouble Quote
THe_DeTAiL3R Posted January 9, 2006 Report Posted January 9, 2006 There are at least 2 different versions of intake gasket for the 3100. From 94-99? there were 2 styles I know that for sure. The early 3100s (like mine) had no pushrod guides, aside from that they look the same (there might be other difference I didn't take it out of the package to compare that closely). late 95 and 96+ and up got the pushrod guides, I'm not sure if 00+? got another design. Quote
96mcls Posted January 9, 2006 Report Posted January 9, 2006 yeah, f 399's car needs the ones with pushrod guides. we compared the two at o reillys and the one W/O guides looks like the dowel pin will work, but it's just they don't have the pushrod guides. i noticed some of the cars with out the guides on the gasket had a little metal bracket bolted to the head with the push rod guides Quote
