Jeez, that sucks. Might only be a head gasket though, which would cause the same symtoms. If you did not run your engine too long with that problem, the engine should still be OK. If you haven't gone back to the dealer to get the work done yet, you may want to try the Barrs stop leak or...
i am in complete agreement with you. you should not have to do this. from what i read, some of the aluminum block engines gm built had too much "porosity" and they had to use this treatment to completely seal the internals off from oil seepage. go figure. but, it seems that is also worked...
well, you know the saying about "opinions".
is standard s.o.p. to put these into some gm engines as a matter of routine when they were 1. built, and 2. when a coolant change it done.
is cheap, easy to do, and if it solves the problem, you save huge $.
gm makes special coolant sealing tablets that may help. they are made of, believe it or not, crushed walnut shells. check with you dealer, they should have in their parts dept. the fibers from the walnut shell materials go into suspension in the coolant then act to form a "plug" at the site...
mine was a bad shock. factory shock in front went at around 85k on my '00 5.3L. replaced with some rather cheap gabriel gas shocks (i think they were $30 ea) and noise went away. don't laugh at the cheap shocks, they're still ok at 2 yrs out and work fine. will put in better ones at some...
1. Transfer case issue? Known problem. Could try a fluid change if this has not been done (GM Trac II fluid only in these)
2. Take a look at possibly switching dif fluids to Redline "Shockproof" type gear oil, supposed to help on older dif gears that have some wear issues. Go to their site...
Most fluids that have a maintenance change interval are ones with addtitive packages in them (such as oil, rad coolant, trans fluid, etc) that get used up over the time interval specified by the change schedule.
They also can break down, and hold a lot of crap in suspension.
You seem to...
There's Chevron Injector Cleaner that says "includes Techron", and then there's straight Techron. I've purchased the straight in both 12 and 20 oz bottles.
Redline makes good stuff I think, I've used their Redline Injector Cleaner also, and it is cheaper to use as one bottle (usually pay...
Tehcron is good stuff, used it for years on my '00 Tahoe 5.3L since purchased new, now at just over 100K mi.'s, still running great on original plugs and have never done anything at all on the engine.
Put in one of the large bottles (20 OZ.) pure techron (not the diluted version) at every oil...
I agree.
Most recently, the rear wiper motor on my truck started to struggle getting the blade to move. I figured that the motor was shot, but before I ordered a new one (you can get a brand new one with no core, with relay board and all for $68.00 - google Dorman Products), I removed it and...
The tubing connector on my rear wiper came apart where it's tucked behind the fuse box in the engine compartment also.
When I replaced the motors though, they were working, but the motor housings were leaking (just old age I guess).
