yeap it would be a nice project for bonniefest i got the parts

so what let the antifreeze leak out?

It knocks because it it'* to hot. The dieseling sound is from this as well. Your motor is so hot inside, that it'* prematurely firing. Your computer probably can't even pull enough timing to save itself.

Pull the stat, and run around the block.

Hey all...I'm on the phone with Steve....he said the petcock was loose, missing or out. Kenn ran one over to him. They filled it up...steve let it warm up a bit and started down the road. It started knocking and losing power w/in a 1/2 block.

From talking to him it sounds like it may have gotten so hot it did warp a head or something. Coolant temp shot up quick and tons of noise.

He'* going to bring it to a mechanic and have it looked at. Soon he will be back on the road oppressing the N/A'*

Steve... I know I'm joining in a little late but could you have put the T-stat in upside down?? It would be possible to do and it would make the car run red hot like you described. You can find the parts to do a rebuild at a parts yard pretty cheap.

One other thing is there water in the oil?? If so you have a blown head gasket.

And I beg to differ on the dex-cool statement. I had my bonny flushed out and put in the prestone antifreeze you can use with any color. My mechanic said the dex-cool is only good for turning to sludge in the radiator. Every one I have talked to about the dex-cool says the same thing.

My car is running great after the complete flush. Before the flush it was causing a slight leak at the TB. Just my two cents.

If they are warped.... Don't pay to have the heads milled, you can get performance onces on the car for less then that.

I'm betting it overheated and the radiator cap didn't vent, causing the petcock to blow out under pressure.

My money would be on a failed water pump causing this to begin with, and that looks more likely considering how quickly it overheated today.

It also sounds like rod knock. Time to drop the oil pan.

wow STEVE, pay attention to your gauges next time!!!!!!!!!!!!!!!!!!!!!! they are there for a reason
this whole situation could have prrobbaly been prevented if you did that? i overheated my car once driving on the freeway when the water pump blewi shut it down as soon as i seen the temp go above normal i knew something was wrong

In talking with Steve last night he told me the story. Basically sounds like whatever happened the petcock blew (prolly WP like Bill said) then all the coolant leaked out.

Without water the temp sensor may not read until some water passes by. Either way sounds like he'* getting exhaust into the coolant which is causing it to heat up so quick and now with the knocking it'* smoked.

Steve is this your first kill?

If the petcock blew, the ECT would have still showed an overheated condition. That'* why they put the sensors in the LIM.
