My car has been over heating since I got a tune at the OK Shootout.
It was tuned with low octain gas 89. This was the highest octane
I could find in Oklahoma.
During tune Dave D. said that he thought it was detonating. I could
not hear it. But I am hard hearing. And could smell anti-freeze.
I had zero loss of coolant(was running straight water). So I thought
maybe the head lifted then resealed while on the dyno. I drove back
home To IL. the car ran warmer after chip tune.
After I got home a I ran the car hard to blow the headgasket out
.But it would never blow completely out, but I think the head lifted
then resealed,because I could smell coolant. But never lost any
coolant.
So I pulled the heads off. Could not see any head gasket damage.
Install a new head gasket. but car ran even warmer .I can't drive
the car over 50 MPH. If I go 60 MPH the temp guage max out.
So I took the heads off again because of the over heating. No
sign of head gasket problems. checked the heads they looked
just fine checked the block, block checks just fine. I think that
I check out ever part ,nothing wrong.
So I pulled the heads of again, inpected every thing that I could think
of, had heads pressure tested, I found no problems. replaced head
gaskets again.
I can,t find one problem. I just got it going again and tried the
car out today again. If i drive 45MPH the temp guage gos
pass the L in normal. If I floor the car for less than one second
the temp guage gos max. and I can smell coolant. but no leaks
no coolant loss.Wet around radiator cap.
I have replaced the radiator cap three times.
I have tried three new thermostats.
I would install my old chip, but it got takin from my car
during the dyno shootout in Oklahoma. So thats not an option.
damm theves are every where.
Anyone have an idea of what to do next. I have tried for two
years now to get the car running right, but no luck yet.
out of ideas.
Thanks Randy
PS Forgot it has always blown black smoke since SCT chip install.
From the beginning up to today.
