so i fired up the iroc after the hsr swap, was looking forward to a drive around the block @ least after over a year of the car sitting. but turn out i have a water leak. it comes from the rear passenger side of the intake, anyone else have this same issue, what gaskets should i used, i just bought regular one from auto zone, now i will have to retake everything off sucks

 

We used Felpro 1205 did you use enough black RTV sealant on the rear wall?

 

im beggining to think i didnt use enough rtv il be sure to order a set of the 1205 gaskets and use more then plenty rtv this time, just maybe wondering if leaks there would be a problem

 

yeah a water leak is uncommon at the rear. Oil i can see that happening from not enough rtv, but water is different. The gaskets should seal that port up

This time get felpro 1205's and use alittle layer of RTV on both sides of the gasket around the water ports. Also lay a nice fat bead on both walls of the motor.

I've used right stuff gasket maker on both my motors and never had a problem tho. I like rightstuff better than RTV for the rear walls and water ports

 

I always order 2 sets of intake gaskets just in case I have a leak and have to re-install the intake manifold.

 

You do not want to use a bead of RTV around the water ports. Just smear some silicone sealant using your finger tip around the water port on both sides of the gasket. This will seal very nicely. Too much sealant is not a good idea because of the volume of sealant you have to push around when you torque down the intake.

 

thanks 4 the input, i believe i used enough rtv might have been wrong gasket i used cuz i sure do get a good chunk of water leaking, i'l get the 1205 felpro's from summit thanks for the advice i hope not to have the same problem next time around, but now im pondering since i have redo everything all over again if i should replace my stock heads just a thought....

 

yeah thats what i ment, just a little layer. I've done that on all my builds so far and it works
