Intake valley seal

Post by briansbronco »

So I'm not real happy about it but apparently in my haste to get my new intake and carb on my truck I didn't let the gasket sealer setup enough before cranking my engine. Apparently it blew out a little on the front and a small section on the back. I know in the past I usually let it sit for 24 hours but I think the cold effected cure time. So how many of you guys have made a repair in this area without removing the intake? I'm thinking of cleaning it really well with alcohol and applying more gasket maker through a nozzle into the suspect area, letting it cure properly. It's not that bad but I did notice it so it needs to be addressed before it decides to become a oil leak. At this point I don't have any oil coming out, just a little smoke.

I've never had any luck doing this. You just can't seem to get it clean enough. If it won't take very long it's worth a try though, worst come to worst you have to pull the intake. Your not gonna hurt it.

Brake cleaner to degrease and use a vacuum cleaner sucking at the valve cover to draw the sealant into the gap. It's also best to warm the engine before doing the work.

That's a good idea. Wouldn't have thought of that one. As far as I can tell it's just two small areas, one front and one back. If it ends up being much trouble I will just pull the intake. I just hate that as it was just off.... :cuss:

It's not the oil leaks that would bother me as much as the vacuum leaks. Airtight and oil tight are 2 different things. Of course you can drown it in sealant... I would just pull it off and do it again, patiently. Make sure the mating surfaces are super clean too. Proper curing doesn't accomplish much if it's cured to a patch of dirt or grease.
