i just got the upper and lower intake manifold gaskets replaced. i didnt do it, it was honestly too much for me so i let my mechanic deal with it. he did it. it didnt work. when i called to tell them, he said it was a silicone gasket not an actual gasket. but when i look on threads here i see brands like fel pro/ etc. does using silicone make sense or should an actual gasket have been used

 

Actual gaskets. Idk what they were smoking if they just used silicone on the mating surfaces

 

There are a couple plastic/rubber gaskets that seal the intake to the head. I didn't use silicone between the two, but did use a bit on the front and rear where the intake meets the block.

 

If he only used silicone and no gaskets he is not a mechanic..

 

yea thats what i thought, because he hasnt got paid yet and hasnt until this ****s fixed...meaning if he has to take it apart oh well not my problem. in your opinion(s) what is the best gasket for upper and lower intake?

and trust me, this guy i swear ill go in to get my tires rotated, and 2 weeks later something else goes wrong, at 85/hr i could go to a gmc dealer probably cheaper

 

definitely need to find a new repair place,good luck. Felpro gaskets...

 

FEL-PRO Part # MS98002T

 

thank you guys for the quick response. and trust me after this im definitely never going back to this guy

 

talked to him today. he said he used fel pro gaskets. idk what the hell he was saying the other say about silicone but who knows...is there any way to tell without taking it apart if thats true?

 

Honestly, if he even just SAID it was silicone gaskets and actually used FelPro's he's still questionable. And no, without taking the intake off there's no way of knowing for sure. If it were me (well I do it myself but either way) I'd have it towed to a DIFFERENT shop and redone. And yes. Use the Felpro gaskets. But when you say it didn't work...what is there still antifreeze going into the oil? If he meant silicone on the UPPER intake gasket. I Could see him doing that as it's only and air gasket (between the actual manifold and the plenum). But still not recommended. Either way. I agree with 4x4GS10B, he should not be working on vehicles.
