OK . I HAVE 2 ND GEN T2 . IT BUBBLES AND OVERHEATS AT THE RADIATOR. I TOOK MOTOR OUT , AND STRIPPED IT . ITS GOT GOOD COOLANT PRESSURE .....NEW RAD. , PUMP , THERM. O RINGS , ECT . I PUT MOTOR BACK IN . STILL BUBBLES AND OVERHEATS . WHF ??? PLEZ . HELP!!

 

does it show on the gauge it is over heating? and is it bubbling out of the rad?

 

yes .................also its gettin coolant into the i. c . and lit . in the oil . none out ***.

 

Maybe the system is clogged somewhere? Maybe a weak Radiator Cap?

Coolant into the Intercooler? Little in the oil? What~?

 

blown head gasket

 

Really? probably just threw a rod.

 

one of the cylinders isnt firing

 

thx

 

^^ we knew these tips might help

 

probably just the valve seats. those can cause all sorts of problems

 

Non-interference motor. Probably skipped a tooth on the camgear and smashed valves. Total engine replacement needed.

 

^^ that sounds like the most likely culprit

 

bruce fix your car!!!

 

U dummys are a lot of help !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!11111111

 

i noes !!! propr . gramer FTW!!!!!!!one one !! !@

 

stupid question which could EASILY be the problem....
have you considered the turbo coolent passages are cracked and leaking into pressure side of intercooler plumbing...
this would explain the antifreeze in the Intercooler but non out the *** AND bubbling in the radiator...
this might also explain how the keg passed the coolent pressure test... the turbo was probably NOT hooked up.

the overheating i'm not sure,,, maybe turbo not spinning causing excessive back-pressure and thus more heat retained in engine.... THOUGHTS??

This is all SUPER EASY to check of course... just disconnect pressure side of turbo, let it idle and see if problem persists / or see if antifreeze comes out the turbo.

Best of luck

nah.. pretty sure its a bad rod. LOL.

 

now thats the help i need .. thx chris . spyder said the same thing , but i aplied air to system today . with maf off . no coolant came from turbo .,.. how bout tb .? leakin into system ? ............. i dont think its a rod , head gasket , vavle , piston , or a cracked cylinder wall . .... but thanks ,,,,,,,,,,, thanks alot . :{ ..

 

you get this figured out yet bruce, I got mine back on the road today.

 

could be collapsed lifters... they always do that.

 

Close plez.

 

so u pressure test the block what psi and how long u let it sit?

 

Ya Chris I did a coolant pressure test on his block. The test turned out fine. Held 30 psi overnight.

 

Urban legend has it that a new radiator may, on occasion, have a trapped air bubble within which may impede the coolant flow and cause overheating. This same scenario of the trapped bubble may also be applicable to the engine coolant passages.

Either that, or bad blinker fluid.

hey blinker fluid is hard to find, so heres the link
