Intake gasket

Maybe a pic will help

Mike,

Check the bottom of the intake manifold for a crack or a casting pit that goes through into an intake runner. An intake vacuum leak check could have been done before the intake manifold was removed. It wouldn't tell you where the leak was, but it would point you towards or away from the intake.

I hope that's not a crack at the lower left of your intake port.

John,

No, thats not a crack, just a funny spot in the pic. I dont see any flaws that would create a leak. Wish I could get a closer pic but my little camera wont do it. This Fel Pro gasket lasted a good 2 years. Dan Jones recommends Victor Reinz gaskets. If I can find the Victor gasket, I will try it this time.

Found the Victor gaskets at Car Quest.
No one else around here carries that brand.
Part # 95078SG

Who carries Victor Reinz gaskets online?

Mike, re your oil film in the port, are you sure the valve stem seals are good? FWIW, stock 'seals' really aren't- they're neoprene umbrellas that ride up/down with the valve & let oil run down the valve stems, if one of the small drainback ports partially plugs up & allows oil levels to rise in the rocker covers. A high pressure or high vol oil pump will also cause this from pumping too much oil upstairs, as will long term valve guide wear. The stock rubber umbrellas also harden and disintegrate with time, eliminating what little 'sealing' they do.
When I rebuilt the 351-C, I installed all-teflon 'Perfect Circle' valve stem seals- now in their 20th year and no leakage.

Jack, No those are CHI heads with PC seals. Only have 3-4K miles on it. Just finished putting the transaxle back in. Gonna fire it up this week. Im confident that gasket was the source of my right bank smoke.

Hey Mike,
Have you checked your angles, should be exactly the same. can be checked with no gaskets, pushed to one side and feeler checked, then to the otherside. could be a little out.

Mark

Mark,

Yes, I laid the intake on there without gaskets. Started 6 bolts. It lays right down in there and the angles are right on.
Now for the bad part-----I just fired it up....Sounds great but still smokes. Man im bummed. I thought I was getting caught up on my Pantera winter projects. I will pull the intake again and have a look. If I dont see anything, I guess the engine will be coming out.

Mike

The intake is back off and the Victor gaskets arent sealing. Anyone else have this kind of trouble ??

On the plus side tho--pulled out a lifter (solid w/oil hole) and absolutely NO wear. Beehive springs. I run Castrol dino with 2 bottles ZDDPlus.

Are you using the end gaskets that come in the set? If so, maybe they are too thick.

No--Im using Right Stuff silicone on the ends. Not sure what to do next. I have a set of MrGasket ultra seal #5836 ordered. They are similar to the Fel Pro #1228 that I first had on there.
