I think i have a cracked block

[k5freak44]

Alright heres my symptoms,

smoke on startup when cool

sweet smelling exhaust

very low coolant (i filled it back up)

nasty gunk all over the block by the rear pass sparkplug

not alot but a tiny bit of water in the pass tailpipe

engine stumbles until its warm


What do you think?

Thanks Again

could be cracked head, cracked block, or most likely a blown head gasket.

the oil on the head by the plug is most likely from a leaky vavle cover gasket.

i see the oil from the valve cover gaskets but this stuff i see is isolated around one sparkplug and i dosent start at the valve covers.

anyone esle?

thanks

I would guess that you probably have a blown head gasket.

Put a pressure test on it...Go to Autozone, Advance, whatever and rent a pressure tester.

Cracked block is an awfully serious problem to be jumping to the conclusion of....

like he said, test your compression. Is it only on one side or is it both??

 

[k5freak44]

both sides smoke, one side has water in the pipe and it is the same side with all the gunk around the sparkplug

thanks guys

is there water in the oil?

 

[k5freak44]

nope no water in the oil

is the water there all the time or upon start up..it is normal for some to be there if it hasnt reached proper temps..byproduct of burning gas..

 

[PsychoticDeadGuy]

could it be bad threads on the plug or in the block? cracked or broken plug?

I dont know when the water is there but its not very much. Everything is happening on my passenger side, and i have true duals so i am only seeing water and smoke on one side.

I ONLY get smoke on startup tho, out of the pass. tailpipe
