Mike94531 Posted November 29, 2008 Report Share Posted November 29, 2008 Got the news from the wife on Wed that as she drove down our street the temp gauge pegs, oil light and check engine light go on and car is now running like cr@p.I get home, pull dipstick, what a lovely sign to see water mixed in with the oil Anyways, spent way too many hours yesterday taking the head off, spent more time on one stupid nut trying to get the turbo off than I'd like to admit in public !!!Head is off, I see no obvious signs of failure of the HG or the head, I'll still take the head to the machine shop and have it checked out, hopefully they are open today as they said they would be.Car has 168K miles and a bunch of oil in the intake, going to rebuild the turbo, any recommendations for kits or are the eBay kits okay??I bought new headbolts, are they still torque to angle?

Chilled man Posted November 29, 2008 Report Share Posted November 29, 2008 I would replace the head since it would suck to get it on and then the valve seals be all but shot also . but while doing this do TbletWaterpump tensoners Link to comment Share on other sites More sharing options...

Mike94531 Posted November 29, 2008 Author Report Share Posted November 29, 2008 no upgrades right now, need it back on the road ASAP, motors are cheap enough I think I'll grab an extra one and start to go thru that once I finish building my new 242 motor....good call on the vac lines, many are on their way out...the plastic covers for much of the wiring just crumbled at the slightest touch, so those too will need replacing..belts and tensioners and waterpump, I replaced about 20K mile ago...installing new raditor and all new hoses as well this time around...

Cal3thousand Posted November 29, 2008 Report Share Posted November 29, 2008 Head bolts still torque to 130 degrees on the final stage. That's after 20nm and 60nm IIRC. Link to comment Share on other sites More sharing options...
Keaton85 Posted November 29, 2008 Report Share Posted November 29, 2008 Ok heres the run down, this is what I would do....Keep this in mind. The head gaskets are REALLY REALLY RARE to fail...RARE!! so it might have not even been that. Thats besides the point..Replace:Valve stem sealsCam sealsHead gasketIntake & exhaust gasketsthermastattemp sensorComplete PCV system (Replace with NEW, I repeat NEW... AGAIN... NEW NEW NEW!)Timing belt even though it was replace at 20K, I would do it just due to the stress of taking it off and on.Top motor mount if its bad. (good time)Don't:Rebuild the turboReinstall the old PCV systemDo:Use the old head bolts... they are good for one more time... Link to comment Share on other sites More sharing options...
Keaton85 Posted November 29, 2008 Report Share Posted November 29, 2008 As for tightening....Work from the center outStage-1: Tighten to 20NMStage-2: Tighten to 60NMStage-3: 130 degreesJust like stated above Link to comment Share on other sites More sharing options...
Mike94531 Posted November 30, 2008 Author Report Share Posted November 30, 2008 Why no rebuild of the turbo? It will need it sooner or later correct??I just figure since I have it removed, it would be a good time.I'll have to look at the manual to figure out what all is part of the PCV system, I broke a few plastic tubes that went from the turbo inlet and wrapped around the head, I think they go someplace below the intake which I have not fully removed yet.Head is shaved, it was off a good .012" with a precision straight edge placed against it.Bought new head bolts already, guess I could return them to help offset the cost of more items I'll need to add to my list for the R&R of the head.

Keaton85 Posted November 30, 2008 Report Share Posted November 30, 2008 If you know what you are doing and want to spend $70 bucks on the rebuild kit then sure go for it. But if you dont know what you are doing then you are going to be shooting a lot of F-bombs out when you take the turbo apart.How much play is there in the turbo?Just keep in mind that these turbos don't ever really fail unless you really mistreat them.Edit: that tube that you broke it the PCV tube running under the intake to the oil trap... do some research on replacing that system.

Mike94531 Posted November 30, 2008 Author Report Share Posted November 30, 2008 A few more dozen or so f-bombs won't hurt anyone, I just make sure the kids are in the house Yep, just read a PCV article here and on Bay-13, still need to figure out where that last bolt is holding my intake manifold on is, feels like it is on a rubber isolator or something.

Keaton85 Posted November 30, 2008 Report Share Posted November 30, 2008 there is a bracket under the intake manifold holding it on... Link to comment Share on other sites More sharing options...
