Recommended Posts

Just got a used GTP, owner's manual had complete service history up to 80,000 miles. Found it interesting, learned some things. Here it is, I left out more common stuff like air filters and oil changes:

 

Bought new 11 miles 7/7/95 (car is a '95)

 

10,366 miles 1/12/96 replaced rear brakes

 

15,780 miles 4/25/96 replaced front brakes

 

34,653 miles 4/15/97 replaced back brakes and rotors

 

45,300 miles 11/23/97 replaced ignition module

 

49.548 miles 2/7/98 replaced front brakes and rotors

 

50,985 miles 3/2/98 replaced all 4 tires

 

51,560 miles 3/9/98 front end aligned

 

57,187 miles 6/17/98 replaced rear brakes

 

61,300 miles 8/28/98 replaced alternator and acc. drive belt

 

68,192 miles 2/23/99 changed oil found white milk in oil (??)

 

69,264 miles no date given- replaced front brakes

 

72,464 miles 11/2/99 replaced rear brakes

 

77,000 miles 10/25/99 replaced alternator AGAIN warranty GM

 

no mileage given, August 2000- replaced intake manifold

 

END OF SERVICE ENTRIES.

 

A few deductions: this car used some brakes, and lots of alternators ! Last entry for a lifetime K&N air filter was 80,199 miles on 10/26/00----there's 102K on the clock now. I see an oil leak underneath motor/trans on pass. side. Front seal ?? Gotta check it out.

 

I checked the timing belt, looks OK. Any similar experiences ?? Wonder what they did about the "white milk" in the oil ?? :lol: :wink:

That milky stuff in the oil is not a good sign!!!!! Check the power steering lines to make sure they're not leaking. PITA to fix too! :) :)

The milky oil sounds scary!!! But I guess if the oil has been fine the past 40k miles, it was probably a fluke.

I noticed oil pump drive and power steering hose weren't listed, which in a way is bad, because that means you'll be fixing those before too long.

I can tell you horror stories!

 

Some tips:

 

Rotate the engine to gain access to the rack. Dropping the engine frame will help. I skip this, though.

 

Use crow foot sockets and a long extension to access the fittings at the rack.

 

Line up the hoses and fittings and then secure the PS pump to the bracket.

I didn't think changing the power steering line was all that bad!

The most difficult part was removing/installing the pinch bolt. It wouldn't have been hard to do if it hadn't been for that hard vinyl boot covering it. Removing/installing the pinch bolt was 1000x easier on my '89 which has a softer boot.

Lowering the subframe and disconnecting the downpipe was no problem either. After doing those things, removing and installing the new PS hose was pretty straightforward.

 

What I'm dreading, is changing the timing belt. To do that while resetting timing with the hold down tools requires pulling the plenum, and I HATE pulling the 3.4 DOHC plenum. There's just so much attached to it, behind it, around it, etc. Plus it's a heavy SOB and not easy to reinstall since I had to hold it with one hand while pushing hoses, EGR, etc. out of the way with the other hand.

Yeah I have to replace my timing belt soon too. I'll do it at work though. Thats where the air tools and lifts are. 8) 8)
