**edit** should read cylinders 4&6! What would be ANY causes of oil in 2 adjacent cylinders? 4&6 are soaked and burning oil bad. This is somewhat of a continuation of a thread about my aluminum intake not sealing at all. Long story longer, I attempted to install a used TA intake and could not get it to seal no matter what I did, would suck oil into multiple intake ports, tried valley pan, different sealers, everything thats been recommended here, even .060 composite gaskets. I gave up on and put my stock intake back on as ive done many times, but now its burning oil bad from #4/6 cylinders, all others are dry. Ive had this thing on and off 5 times thinking its not sealing and using different recommended techniques every time. ive had this intake off MANY times over the years, always installed it the same way and never had a sealing issue so im wondering if something else is going on?? It starts smoking progressively as it warms up and gets very heavy if i rev it up, also there at idle and never goes away. ive put in clean plugs and they come out soaked with oil everytime. all other plugs are dry. compression on those 2 are 145 WHat else should i look for? im at a loss here and not sure what the possibilities are. it ran perfect until i pulled it and tried the TA. im pretty bummed out because its been a great engine and now all of a sudden I cant get this to stop. ANY advice
Thats what I initially assumed so i kept it running for awhile, revving as well, hopping to clear it out but never diminishes, so i shut it down and pull the plugs and they always come out soaked again, and looks like fresh oil each time. how long could it take to clear out if that IS the case? just seems odd that all others are dry and clean now when they were the ones oil soaked as well from the TA intake attempt. now its just consistently isolated to these 2 cylinders even after removal and reseal
I just thought maybe something was blocking the oil from draining back and it was sitting up in the head, and getting dragged down the guides. Try some seafoam down the carburetor slowly.
ok i have a bottle here i'll give it a shot. I'll pull the valve cover as well, what should I look for ?
Anything that might block oil from draining back. Maybe some old gasket material, or a small rag you left in there by mistake. It's a long shot, but if you are going to look.
everything looks normal under the valve cover. ran some seafoam through it and once that white smoke burned off its back to blue
Do you have any gas in your oil? Not sure if or how it could happen but is there any way with the bad gaskets that 2&4 cylinders could have gotten washed down? If so I believe there would be some gas in the oil. Is there any problem with the head surface at 2&4 that oil could be sucked in from the valley? Did you see any problems with the gasket in that area?
Its STILL doing this WITH the iron intake back on it? You checked the drain back holes in the head as Larry suggested so your good there. This may sound odd, but it sounds like a couple of your valve stem (intake) seals are shot. Have they ever been replaced? Have the springs ever been changed. Do you have the ability to remove those springs for the affected cylinders and have a look at 'em? I know this is completely unrelated to your intake issue, but for some reason, things like this " just happen"
Bad trans vacuum modulators will make lots of white smoke. Had one go bad years ago.. Looked like James Bond going down the road...lol
I don't think any gas in the oil. Doesnt really smell like it. I'm pulling the intake again and will look closely at the gasket. Head surface looks clean and smooth. Heads were rebuilt a couple yrs ago. yeah man! I dont get where its going wrong. Ive had these intakes on and off at least 6 times in the past couple weeks. My back isnt happy lol. Heads were rebuilt with new every thing but the rocker assembly a few yrs ago so im assuming everythings fine with springs/stem seals
Im sorry i just realized i made a typo. Its cylinders 4 and 6 (center), not 2/4. Not sure if that makes a difference. Pulled the intake again and just looking around i see this on top of my #4 valve (one of the oily cylinders) Looks like its scored around the top. Is that normal?? I dont see it on the others.
Did the intake look oily? 2 and 6 are still different planes of the intake. Try the plugs in a different cylinder. Did you find any thing wit the gasket?
When using the composite gaskets I sprayed them with the copper high tack so they would stick to the heads before putting on the intake. What was used for valley pan with the composite gaskets? did you trim an old one or use one from AM&P like I did. If you trimmed the pan to fit the bottom of engine above cam then put on the composite gaskets the bottom can get pinched by the old valley pan. I ran into this before I used the special pan made by AM&P. Try the TA intake again it should be ok you are having the same thing with both so why break your back with the stock one. I put 2 pics in here to look at where the trimmed old intake can pinch up into the intake track if not trimmed close enough. The other pic is with the AM&P valley pan replacement then you just use the TA composite gaskets, they do have 3 different thicknesses so be careful there. you may need the .060 ones I use the .015 ones and there is I think a .030 set. You probably need .030 or the .060. This pan has the intake runner holes trimmed off this was the old way of doing this with composite gaskets. That cutout lip above goes against the heads. with a 1/16 metal lip that goes on top of the head to help hold it in place. Above is where the gasket gets pinched from the intake squeezing down on the gasket and the metal from the trimmed valley pan at that lip in above pic. This AM&P pan is what replaced the old pan set up. This got rid of the gasket getting pinched and the possibility of the intake leaking from the extra material at the gasket and the trimmed metal valley pan. I put those big pins in the engine there too so I can just drop the intake onto the engine nice and straight, then pulled them back out later.
