Default CVVT Gear finally replaced.

I have had an oil leak for the past year and have been trying to detect where it was coming from, I had a few shops misdiagnose the leak. After reading here, I did suspect that it was most likely the CVVT gear. I managed to drive it a whole year, I wonder why I never got thrown a CEL at any time. I was careful, monitored it and a little stupid for not taking care of it earlier.

I now have to replace the passenger side axle as well as control arm from the oil that dripped over them..

I am lucky the belt never slipped, and I had both front and real seal and camshaft plug replaced as well as timing belt and tension-er.

The only reason I waited so long was because the timing belt had been done with everything 30k miles beforehand.

I'd go buy a lottery ticket! Maybe that luck will rub off?

Funny you should reply, I was thinking of you when I wrote the above, I think you mentioned 8 valves being destroyed.

Yeah I was kinda lucky but am glad to have it finally done.

I learned the hard way about that oil leak. The wife told me about it but I was reluctant to explore it further. Boy did it bite me. Glad you got yours fixed.

I knew from my driveway but was reluctant also because the timing belt, seals, water pump and everything had been done 30k beforehand. I really was not sure where the leak was coming from but after reading here about the cvvt gear causing problems, I was close to positive it was the culprit.

Thanks to all the knowledge here! Merry Christmas!
