Engine dies......

[Left Coast]

The house going from the maf boot to the intake manifold was ripped at the clamp. Does anyone know the size of the line. Need to go to napa and get a replacement.

Is that the one from the idle air valve? Smoke test should have showed this. Close inspection of all hoses probably would have also. Take the old hose in with you. Some hoses are expanded at the ends for the fittings or need to be molded in a certain shape to fit the path they must travel in. Some also must have a certain sidewall thickness to prevent collapse. You can probably buy the correct direct fit hose on amazon or eBay or FCP euro or ECS.

Yeah fcp but don't have the down time to wait for a line. I am going to take it to napa and see what happens.

Might find a radiator hose that will work if they let you in the back to look. You can also splice something together temporarily with a plastic barb connector (coolant repair part) and a scrap section of hose.

After replacing the ICV hose and MAF sensor. All my CEL codes cleared. So far they haven't come back. Even stranger is my ABS light also went off. Don't know how that's connected but what ever. Now just got to locate an oil leak that keeps pooling up on my ac compressor.

[pbonsalb]

Oil leak is probably from the head where the timing cover meets the block. Common if headgasket was it installed correctly with a little sealant under it in that area. Could also be simply from a leaking chain tensioner. Clean the area then trace fresh oil residue.

HG was replaced by po. Really hope it's not that...

You might be able to clean really well and JBWeld the exterior seam to slow or stop it. You only need to go down maybe 6 inches from the corner along the seam towards the header and maybe 3 inches around the corner up toward the vanos. Sometimes helps sometimes does not but you don’t want to replace the HG unless you have to. Also check under the chain tensioner.

ok. i will have to pull off the coolent hose going in front of the vanos to get a good look. then go from there. i had replaced my valve cover gasket originally thinking that is where it was coming from.

[pbonsalb]

I would not pull off any hoses. Just clean and then look the next day using an inspection mirror if necessary to see around stuff.

[Left Coast]

I cleaned what I could but there is a decent amount of build up behind radiator hose in front of the vanos.

[Left Coast]

I cleaned it up last night. This is after a 60 mile drive.

The head is not very clean, but it looks like oil was coming from the valve cover gasket and dripping down. If it was only lower down where the block meets the head, I’d suspect the headgasket at the passenger front corner of the head.

[Left Coast]

There is a lot of oil build up on front of the vanos. I just replaced my valve cover gasket 3 days ago thinking it was from that.

[pbonsalb]

Maybe it’s old from before you changed the valve cover gasket.

[Left Coast]

Yeah I think it is. I should be able to pull the valve cover with out messing up the gasket apply a little more rtv. And hope for the best.

[pbonsalb]

The valve cover does not need much rtv. Only at the vanos to head joint and around the half moons in the rear. You would see fresh oil if yours was leaking that high up in the front. Take the car into a DIY car wash with 3 cans of engine degreaser. Pop the hood, empty 1-2 cans onto the engine block and 1-2 cans under the car aimed at the oil pan and trans and lower engine. Let sit 2 minutes. Then use low pressure rinse to clean all the soap off.

After more searching the the far reaches of the interwebs. I am starting to think the oil leak is from the timing bolt or drain plug.
