2F head
Unfortunately that vintage of head does tend to crack so I agree with most of the above. Good across-the-board compression numbers like yours wouldn't be there if the head gasket leaked compression into the coolant jacket, now, would they? Plus it would be overheating like a mofo. My...
They say glue the gasket on the block but I always glue my gaskets on the removable part, like the pan or valve cover. It can save a lot of grief if you ever have to remove the part later. Scraping gasket material off a block can really be a nightmare & I've had no problems, but both surfaces...
Just a little something I'd like to pass along: when you change the hydraulics, do the master first, then the slave. Otherwise, you could be bleeding the sucker for 2 days, like I was because I pulled master & slave at the same time. The fluid can run out the line & get air pockets in it that...
Shoulda
coulda, woulda, it sounds minor to me, too. I hope you didn't do the rebuild because of hesitation. And, $2600 is about what you would pay for labor only, most places, so what exactly was done? An in- frame? Whatever, I agree with you he shoulda done a test drive & given it to you...
Get ready to spend $$$
Idle speed/idle ari control valve sounds bad. Used from Spector, mine cost $250, new they were $500. My problem was a continous high idle. The FSM has a test sequence for it.
Pull all the powertrain and interior worth saving, junk the carcass, & buy a non-rusted unit with a busted engine & trashed interior. You may have to look south a little, but putting that rusted s***box back together simply isn't worth the effort & cost. It would be far, far cheaper to fly to...
Just take the fricking air cleaner off & adjust it. There shouldn't be much if any restriction through there, anyway. If there is, in theory, it causes a rich condition, but I have found theory mostly to be a long way from practical reality. I have seen filters black with dirt on running...
Iffin
I could ever find a decent later 2F head close by for sale, so I could finish my rebuild, I could get you a full report! I know, whiner :crybaby:
Myth buster!
We need our own cable show, Mechanical Myth Busters! All we need now, now that we have the talent, is a sponsor who is willing to give us millions to film cars while we break them, then debate about why & what broke. Surely there must be some giant corporation yearning for a tax...
Is atomized fluid a liquid?
Bald & Red, you're trying to have it both ways. Your theorizing about little gobules acting like BBs contradicts the internal temps that light off the mineral oil assertion. Adding addtional material in the form of non-volitile atomized liquid does make the...
Basic physics
See the General Gas Law. Diesel engines light off exactly because of the high temps resulting from incompressibility of diesel fuel. ATF & brake fluid are mineral oil-based, precisely because of the high temps they must operate under without vaporizing. Even atomized, a spark...
From Wikipedia
Water injection -a method for cooling the combustion chambers of engines by adding water to the incoming fuel-air mixture, allowing for greater compression ratios and largely eliminating the problem of engine knocking. This effectively increases the octane rating of the fuel...
At least you kept the right vehicle.
Rule of thumb for steering play: 1" free travel at steering wheel for non-assisted steering, 2" for assisted. That is, movement of the steering wheel left-to-right before movement is observed at the front wheels. Rack & pinion may be different but I doubt...
How loose?
With power steering you should have a couple inches play at the steering wheel. Don't go messing around with that box until you're sure it's defective. They seldom go bad, unless run dry or overtightened at the adjustment- go by the book when setting it. Usually all that needs...
Water, ATF, brake fluid all work, and the principle is incompressibility of fluids causing high heat that decarbonizes the combustion chamber. Do not try it without having somebody that knows what they are doing show you - it'll be a older pro technician. It is a great way to lower HCs before...
