Blown head gasket
Friday, April 07, 2006 10:18 PM
I think it's gone... I've had small coolant leaks at the front and back of the block since I installed the supercharger.... now I've got no power at all, misfire code P0300, and feels like there's a cylinder or two missing....

I've never done a bad compression check before... now when I put the tester on cyl 2 or 3, I get a hissing sound, and it only gets 100 psi... on #1 or #4, it's 210 psi... Sounds like 2 and 3 are leaking into each other to me... but I'm not sure.

I could try re-torquing the head down.... but it's been a lot of miles since I put the motor together, and I figure it's probably done for....

Ideas?

100psi= no bueno.


I guess you could try and retorque the head. Worth a shot, right?

If you get it torn down to the studs you're better off just going the extra couple steps and replacing the gasket.

Might want to borescope it to make sure its not something more serious though.

replacing the gasket is cake work. replace the gasket and torque the studs nicely and u should be cool

Here we go....





Spot on the back of the supercharger, where the coolant has been spraying out.

Ah well, I finally blew something up

Ah well, got the head off... and it's blown out between cyl 2 and 3... but everything else looks to be OK.

Tomorrow, assuming I can find a head gasket (I've got a new GM one sitting here... not sure if I want to use it or not tho).... and some head studs or bolts..... then I'm good to go!!

Oh man, I am getting nervous I just got done on the final engine assembly of my new motor and I used a felpro. I did not think they sold GM ones.

And who says a head job is easy in a 2.4, its a biatch unless it out of the car.

I haven't uploaded the pics to my web server yet.... too busy working on the car, and now I'm at work

I cleaned it all up, put a new GM (stock) head gasket on, because it was all I had available other than buying a new Fel-Pro (as you can tell, not terribly impressed with them!). Got a set of new Fel-Pro head bolts, since no one around here stocks ARP head studs... so far I'm out a total of $45, plus the two days work... and it's still not back together. In time.... maybe tonight... I'm driving Erin's Neon at the moment.

I would take a Fel-Pro over a GM stock head gasket for a LD, any day. Sorry that happened.

I agree. When we first got the Reaper it had a blown head gasket, but would still run. no visible signs on head damage, while waiting on parts we decided to have it checked, 3 bad valves. 2 bent, but only could see once out of the head. Glad we had ti checked.
