blurping/flushing cooling system and leakdown/comp test

[Maniak]

i am trying to figure out if i am begining to blow a head gasket or if i just have an air bubble in the coolant system. how do i go about burping the system? i would also like to flush the whole system but unsure as to how to do it myself.

i guess it would be a good idea to do a compression/leakdown test before i start taking it apart to replace the head gaskets. although, i was told that doing these tests may not help in showing that the head gasket is blown.

i do not have any traces off coolant in the oil or oil in the coolant reservoir. this problem arose at the track when i made some paces. after the pass, the temp shot up to 240-250. coolant was spewing out of the resevoir. i was thinking maybe i overfilled the system? i was able to drive the car home with no issues. the motor runs fine and stays at about 190 when cruising.

if anyone on here could help me with a compression/leakdown test that would be great.

Mine starts getting hot when idling for a long time or sitting in traffic. I would be curious to hear this answer as well. I am going to try burping the system also.

did the leakdown test and it verified that i have a blown head gasket on the passengers side.

thanks for your help Roy V :biggthump

Hey Maniak, your block is untouched right? No studs, upgraded HG, etc? If you want, I can get the list of what I used on my rebuild. Didn't use the MLS gaskets, but things have held together fine so far (knock on wood).

Decided when you're going to tear it down?

I would go with a factory ford/felpro head gasket and get ARP head studs. I have had no issues with boost and this setup, works great.

Felpro 8548PT2 or Felpro 9333pt1 both available from Autozone for $19.99 each... and a set of head studs!

tryed to search myself but i was unable to find out what the difference is between those 2 gaskets?

will the heads go on without having to pull the motor with those studs?

ive used both... i believe one has a steel fire ring and the other has some other material for the fire ring.. either will do fine..

as far as studs, you can always remove them prior to removing the head. the new studs have allen head recesses on the top..

As mentioned, the 8548pt2 gaskets are a good choice & thats what I went with after my first rebuild using the crappy 1011-2.

For intake gaskets, I decided to go with the Fel Pro MS95952, after reading this:

Much better than the gaskets that came in the FRPP gasket kit.

what intake manifold are u running? does the Fel Pro MS95952 work on the gt-40 intake manifolds?

Stock Cobra heads/lower/upper. From what I read, the Fel Pro MS95952 is listed for the 'newer' 302 motors like explorers. I picked it up @autozone & it was much better than what was listed for a 87-93. At some point autozone updated their records, because when I entered my info on my first rebuild whatever the standard lower gasket was came up, on my second rebuild nearly a year later, the 95952 came up.
