    Re: 99 Oldsmobile alero head gaskets leaking help

    Those numbers look great. The intake gaskets are usually the culprit. As for the push rods, as long as they go back in the same places they came out of, you'll be ok. Yeah, I forget which ones are the longer ones, but don't mix them up. I always take a piece of card board and stick them through it and label intake or exhaust and which cylinder they are from.

    The intake pushrods should have a yellow stripe and the exhaust has a green stripe. Intakes are 5.75" long, exhaust are 6" long.

    Re: 99 Oldsmobile alero head gaskets leaking help

    Another thing that concerns me is the on line on the fuel rail is leakin fuel out of it unsure what that's about. It's the side that doesn't have the regulator on. And also almost all my guages are pegged from me doing the compression test. Hopefully they come back down when all the sensors are plugged back in

    You disconnected the fuel line? If so, it is going to dribble fuel out. If you did not pull the fuel pump fuse or relay, every time you hit the key the pump will pump fuel. Is this what you mean?

    If it's a bad HG leak and you unhook spark and fuel and crank it over with the rad cap off and the throttle propped open, you'll get bubbles coming out the rad cap after a bit of cranking... if it's only a pressure valved leak then maybe not... but if it was a bad leak it would probably be hydrolocking the motor every time you stopped.

    Its only recently it's started getting water in the oil. It has seeped it out of the side of the motor for awhile and has always started right up Everytime.

    Hmmmm. I've never had one leak from there. Not sure how it is sealed at the connection.

    It has an o-ring there if memory serves, its been awhile since I play with one for shitts and giggles. I would find another fuel rail or source one up, then play with yours so see if you can fix it.

    NO on the rockers. You have to pull the pushrods and keep them in order or you will be pulling the heads to fix bent valves.
    Water in the oil is the same for both head gaskets and intake gaskets on these. A block with a crack in the oil passage next to a coolant passage will net you oil in the coolant or a leaky oil cooler inside the radiator.
    If it did not run bad prior, the head gaskets may be fine. Unfortunately, without hearing it run, I can't say. If the numbers are good (135-145 psi) between them all, I would lean towards the intakes causing the leaks and milkshake. Those are my thoughts.
    15 inch pounds and then 30degrees or 30 more inch pounds

    Hold a stubby wrench in a backwards fingertip pincer grip and when it slips out your fingers that's good

    Re: 99 Oldsmobile alero head gaskets leaking help

    real easy to strip probably, what I'd do is eyeball how the gasket compresses, when it starts, that's good enough probably, and if it seeps when you test run, add a 1/6 turn at a time until it don't.

    BTW MkII turbo ES... Some VC gaskets *cough* felpro *cough* are nowhere near as soft as OEM, the one on my Escort, was hard hard rubber, like a mallet head, couldn't compress it, leaked like hell, got about 20ftlb on the bolts before I chickened and let it seep, UNTIL... I got the part from ford, which was like soft licorice... huge difference.

    Smack it, with a stern "Bad GM!" ... checking power and grounds probably wouldn't hurt either.

    They are a non adjustable type. They took the lash adjustment out back in the late 80's or early 90's.

    Damnit....when I deleted the other post, it deleted them all. Try disconnecting the battery or disconnecting the instrument cluster and see if they will reset. If not, you will have to pull the lense and reset them manually.

    Its two O-Rings if I remember correctly. That line goes into that rail a VERY long way. Its quite hard to separate the line from the rail. But you'll have to do it to make it stop leaking. You should be able to pick it up at an auto store I believe. If I were at work I could give you a part number. Its a very common thing actually.

    Re: 99 Oldsmobile alero head gaskets leaking help

    So I would like to thank everyone for the help it's greatly appreciated. The car is all back together and seems to not be getting its fluids mixed together anymore. The fuel rail nut was loose tightened it and it seems good. As for the cluster for the speedo I beat the cluster on the ground upside down and it came back. For the fuel guage I had to drill a tiny hole in the bottom plastic to get my pick in there and fix it. Again thanks alot. And if I ever happen to meet use guys I'll have to buy use a beer
