so head gasket blew im pretty sure, what else?

LooseNuts · 10-07-2009, 12:30 AM

so im pretty sure my headgasket blew. not 100% sure, oil is clean, but the rad isnt getting as hot as it should, and its not building pressure, seems to be loosing coolant, and when i squeeze the rad hose i get allot of bubbles (motor not running) i havnt tried with the motor running cause i work night shift and the exhuast gasket is blown as well so its really loud.truck is an 85 pickup 22re. about 100,000km on the motor. (body/frame has 229,000km)any way, going to try tomorrow monring running the engine and see if my coolant bubbles.if it does, what else should i replace/check while im doing the head gasket?this truck has been nothing but trouble sense i bought it 3 months ago.so far done the timing chain and water pump engine wise for repairs.thanks for any advise (besides burn the truck, cause i jsut might)

Do a compression check.

i dont have a compression tester. would it be wise to drive it to a shop near me if im not sure the condition of it?
there is one about 7 minutes from my place.

Maybe its just an air pocket in the coolant system?

not to sure about hte head gasket now. a buddy came over and took a look at it.
my coolant isnt bubbling even when engine is warm/hot
my plugs are dry
and the water coming from the tail pipe is clear.
and my oil is clean.

it was still steaming from the tail pipe when hot, but the air is pretty chilly here right now so hard to tell. there is a big water spot under the tail pipe (we had it running for about 20 minutes) but its all clear and smells like water.
however, smells like coolant under the hood/around the truck, but cant tell if its the exhaust.

my buddy says just drive it. my thermostat might be stuck open and thats why the rad isnt building allot of pressure and why its staying kinda on the cool side.
little nervouse though cause my mechanical temp gauge crapped out this weekend and my electric one reads half way all the time.

going to see about a leak down test tomorrow or friday.
