Yes sir I did. It’s got a blown head gasket. I pressure checked the closed side and it wouldn’t hold pressure. I then tested for the presence of exhaust in the coolant and it tested positive in a micro second. So this weekend I start the tear down.
Hopefully you get issue resolved quickly. Im curious how many hours on your engine? Is this a quick fix replace gaskets or do you have to rebuild?
The only upgrade I need is the cherrypicker performance upgrade. Unbolt the 496, hook it to a cherry picker and drop a blue motor in. Until I can afford that I am fixing the 496 and running it some more.
Yeah I’m glad too. I’m pretty sure it’s a small blowout because it only rears it’s ugly head when the motor gets up to full temp and ran for a bit. That leads me to believe the gasket is only opening up when the metal expands so I’m hoping for no or minimal damage. We shall see. Break out another thousand right? I thought Harley’s were bad lol
That’s surprising for such a mild, low compression motor. I don’t think I will spring for the head stud kit but I will probably use new head bolts.
you have to replace them no matter what, it is required by GM. a new set is only 38 per side. I just got carried away when I did mine figured if I replaced all the wear part I would get another 500 hrs.
Yeah if they Don’t cost an arm and a leg I will probably go with the studs like you guys are sayingWill be cheap insurance to do the ARP head studs and Cometic MLS head gaskets and be done
How much was the stud kit?
441.99 from summit. I can look at my orders and get you all the P/N you would ever need. I got most of engine parts from summit and Merc parts from Quality here in
head studs
I was being sarcastic. I’ve heard you guys do great work but I’m going to put as little lipstick on that pig as possible until I can afford a real motor.
I think you might be a little ambitious in saying replacing a head gasket on a motor with 220 hours is a band aid. As long as the heads are checked out before re install that motor has lots of life left in it. The source of the initial overheat and coolant loss was the heat exchanger gaskets and those are repaired. Of course I would love to spend the money at boostpower but the 496 is what it is.
Yield To Torque YTT ????
I’m still awaiting that call back on doing my 496 lol.
Peter.......
Shylbntro you were absolutely correct!!!!
I thought mine was air cooled.
isn't a blown head gasket like a wastegate on a turbo????????
