Burning oil + White smoke = Bad Valve Stem Seals?
Hi guys, I've got a 97 prelude h22a and it has been blowing copious amounts of white smoke for a while. From doing some reading around i have been lead to believe the likely cause are bad valve stem seals. These are the symptoms the engine continues to produce:
- White smoke after coming to a stop
- White smoke from accelerating after a stop
- White smoke from accelerating after some deceleration (common especially in higher gear)
- A lot of white smoke when passing 4k rpm and at VTEC
- Strong burning oil smell, which i can smell often without seeing smoke
- Burning excessive amounts of oil (driven approx 1800km over a 5 month period and there was no oil on the dipstick)
I have also noticed that sometimes after not using the car for a while, upon start up the engine might knock a bit like as if a cylinder wasn't firing properly. Also a couple days ago after coming home from a 3wk vacation and i turned on the car and noticed there was significant engine knocking which went away after driving a few kms (maybe oil burnt off from a clogged plug?). All this has led me to believe its due to bad valve stem seals.
Any opinions on this would be much appreciated thanks.
