After taking the heads off and having them hydro-pressure tested, if they test well it would point to a cracked block. So, I started the Lemon Law procedure under Texas law. An ultraviolet dye will make cracks easier to see on a black plastic manifold than a colored dye. A professional inspection is a must before you go any further and may require an engine tear down. Hi Bernard I had or have a Chevy Lumina 3. The pressure was enough to hold it together for a week while I waited on the part and time to put it on. I change tne oil every 3000 miles and its do again.
No matter what product you use, I would make sure it's rated for higher temperatures and plastics. Mike, First off, I hope you had both heads rebuilt and resurfaced at a machine shop. My gasket kit didn't come with it so I had forgotten about the piece. In theory it should be as strong as the original material, but I still haven managed to find anyone who has experience welding anything heavier than a plastic bumper. After completion I started it and it was idleing pretty rough. A cracked manifold leaks coolant into the combustion chamber.
Is the coolant leaking into the engine or out under the throttle body? I gotta get around to uploading that video though. If you click on my blog picture the larger picture will give you a very clear idea of where the coolant's coming from. There is no visible leaks and upon removal of all plugs we found 2 cylinder's plug competely fouled. I did replace the upper intake manifold and still coolant is mixing with the engine oil. This happens because crankcase vapors contain oil, that damages the rubber or plastic, causing hoses and lines to swell and crack. I found this on Ebay: Price is a little steep but it looks promising. I finally got up the courage to clean out the carburetor and install the parts listed above.
I guess I'll have my work done somewhere else from now on. If the lifter noise keeps up, it means you have low oil pressure caused by the coolant contamination. I ripped her apart verbally along with the Service Manager standing with her…who looked pretty sheepish about it. Ok, I got it off. You're fouling out 2 spark plug. I always use a Fel Pro gasket set.
It has been a month since this was filed. Replaced the thermostat today but got it all back together and coolant is shooting out and I see the small crack at the top of the intake manifold where the thermo sits. Buy it, it will work. The whole issue with getting a replacement is that it will likely crack again. That will be your main problem.

Any suggesting would be helpful. So while this is definately a problem, the great majority of folks with this engine will never have to deal with it.

However, as the leak picks up speed drivers realize they have a problem that needs resolving. Rate the quality of this post and help OldNuc reputation points. I was thinking some of those long Q tips down the spark plug holes but would like to know what you do in these situations? For those of you who have suggested I add a donation gizmo to my blog so I may get some recompense for my efforts, I have an alternative since I hate the word donation.

It has been running and driving great, but I actually open my hood every now and again to check my fluids. Located a used intake manifold and it's already on the way, along with new gaskets. I know the union apes will site Toyota's recent recalls. You don't need any special tools. Check out the video in my link. And I know it's never going to break again! Has anyone received their check yet? I have a 2003 LeSabre with the 3. If you see any milky type creamy substance on the underside of the oil filler cap, that's a dead giveaway coolant's seeping into the oil.
It's obvious you're burning oil in 2 cylinder. Didn't look great but couldn't see where that much water could enter. When you get good at a dealership, you start your own shop. So, the shop does not deserve to make any markup on that part? It never failed but I guess if u mix it wrong and or don't prep the surface right anything can happen. If you have any question as to whether you can redo the job correctly take it to a professional now rather than risk damage.
