Sir this is what happen to my intercooler with out catch can ........but i would like to remind you i run my engine hard on road and offroad.

Oils is visible inside the intercooler making it inefficient in cooling down the compress air and found a sticky gunk in the pipes................oil catch can will prevent this to happen and our inter cooler should not have oil inside. I havent heard any problem resulting from using an oil catch can and im using one on my truck too.

Sorry pero hindi ko alam kung pumasok pero 3X ko na sinulat ito, Kapag ba start sa umaga or kahit sa hapon basta matagal na tigil ang sasakyan tapos may white smoke indication na ba ito ng poor compression? Na-confused kasi ako sa sinabi ni Sir DD

Leaks are most often due to a blown/burnt head gasket.

Warps are easy to repair through deck resurfacing. Cracks are difficult. Ask the machine shop for warranty if they will perform a crack repair.

Possible poor compression ito. Hard starting din ba?

Magpa compression test ka para makasigurado.

Marami pang dahilan ang white smoke...

Great pictures.

Small amounts of oil in the intercooler is normal.

Just for info lang sir DD, my car is XUV 2003 MT and still can run up to 150kph at 450rpm and fuel consumtion is ave of 13km/lit sometimes 15 if more on hi-way. Worry ko lang po baka kapag pina compression test ko eh tapos hindi ba pala competent yon gagawa kung ano pa mangyari.

Thank you sir and other forumer here for being generous giving your knowledge!
