Engine 1ZZ-FE Piston Issues?

1ZZ-FE Piston Issues?

any body have problems with pistons 3 and 4? My mechanic said they got stuck but started working again.... Plus compression is low on them...

I had two pistons seize up under boost and snap the connecting rods right off them But I think that had something to do with oiling and heat and all that crap.

how much does it cost to get a compression test done? and where can i get it done?
I'm burning alot of oil.... i wanna see in wat kind of shape my engine is in

some shops wont charge you...only takes a couple of minutes...

A compression test doesn't tell all that much, if your burning alot of oil, what you'll find is that a "dry" test and a "wet" test(oil down plug hole before) wont be very different as a normal test with good rings will show a bigger diferential. Reason being theres already oil because of the bad rings present helping them seal.

A leak down test may show more but again its a crap shoot

if its buring oil its burning oil, you said its going through alot so right away id assume the rings or headgasket.

Some of the early 1ZZFE that have oil consumption issues may also have stuck piston rings and possibly bad valve seals - even with relatively low miles on the clock. Running synthetic motor oils may help, but is no guarantee that there will be no oiling issues. Things got a little better when they adapted VVT-i to the 1ZZFE, but some poeple still had oil control issues. Might try a soak with Auto-Rx or some other products out there. Otherwise - might have to rebuild it.

Or it shows that you took good care of it

ya i switched from syntehic to regular oil bunch of 3 or 4 times so i fucked up my engine.... it better last me for another year or 2....

x2. I take super good care of my car.
