St165 valve, common?

Postby SeatacST165 » Sun Jun 12, 2011 5:27 am

I lost the compression in the 4th cylinder of my st165 1st gen motor!
Is this common for these cars?
Could it be something else?

Thanks!

Common ? ehhh depends on age and mileage. either a valve or ring problem. Did it get overheated at all ?

im not sure if it overheated at all...
got the car from my uncle and im not sure exactly what happened to it while he had it!!
aha i might be the youngest owner on this site(age 15) (:

my grandpa who also owned the car about 4 years ago rebuilt the engine but i can not find any paperwork or receipts to figure out how many miles were on it when the engine was rebuilt, he had it rebuilt at toyota for a little over 5000 i beleive. :doh:

Ha ! you prol are the youngest. My son is 15 also and just started driving on a premit and wanted the alltrac ... he settled for my old Geo prizm ... lol ... free vs high maint cost ... hmmm. But anyway back to your issue. It's going to have to come apart so I would figure how you want to go about taking it apart first ... whole engine out and apart or head off alone ( which is a a bitch but possible ) got to inside her to figure it out 8)
