What did you do to your Maverick or Comet today

How did that happen?

 

Usually caused by too much boost from the turbo.

Possibly a bad blow off valve, or the wastegate got stuck(if he is running a turbo with a wastegate) or he just had too much boost and the engine didnt like it at the moment..

 

Thanks....Im looking into Turbo Charging my project in the very distant future.

 

6.0l diesels are good for that at anything over 30psi boost pressure.



How much boost are you running and is the motor relatively stock?

 

Too much cylinder pressure for the stock tty head bolts ls motors with stock bolts generally dont like to see the pressures that are generated with "higher" boost levels

25 psi when it lifted the heads not uncommon with stock parts at 9.5.1 compression it wasn"t a tune or detonation / air temp issue just a matter of stock tty bolts not handling the clamp load arp studs and mls gaskets are in the future along with some 6 liter heads

I was aware of the risk you can run 20psi on these motors all day long on stock parts ive been doing a little late night racing and do not take a chance on getting outran


The little 350.00 motor that could

 

Would love to see some video of "these late night races".................any serious cash trading hands?????????????????

 

Not yet, ive got one video but my passenger/video man cuts the video off as soon as there headlights dissapear he doent believe in wasting time either lol

383 procharged camaro with a glide and 4.10's from a 20 roll

 

That's impressive!

 

Attempted the second try at painting single stage urathane silver metal flake paint in the motor compartment and this time was able to get it to come out like glass but the flake layed in weird.....have enough for one more try but it that dont work im doing base coat/clear coat in there. On a good note there is so much paint in there now everything is smooth lol

 

Finally able to ship some spindles across "The Pond". Here they come Phil.

 

#1 cyl fire ring egg shaped


can see where the material is pushed "cracked" from the fire ring

 

odd spot in #3 cyl maybe presvious rust?

 

I'd say you dodged the bullet on that one. The fire ring is toast.........
That is an odd spot........from the picture it looks like wall is totally clean under the spot..........and not so clean above. What did the plugs look like?
I see studs in your future and maybe a thicker gasket. Are those gaskets .040 or .060 compressed?

 

got the motor and trans pulled out. next week im goin back with a 5.0 ho and an aod. then the body and interior fun begins.

 

Plugs look great nothing out of line really, talked to a guy about a aluminum 5.3 block tonight would be nice to take that 100 lbs off the nose.i think maybe that cylinder had some water sit in it at one time (i bought it from a salvage yard) debating pulling it and freshining it or slap some gaskets and studs in it

No idea on the gasket thickness there oem gm gaskets this is the first time ive had the heads off.
