Hi everyone- I'm new to this site and forum and have inquired to many locally but can't seem to find an answer.

My 84 190D with approximately 150Ks on it suddenly started blowing' blue smoke from tailpipe; car runs, starts and accelerates as it always has, but now- lots of blue smoke is blowing' out the exhaust, Always seem to had a noisy valve train in this car and I'm curious to know if these engines were known for leaky valve guides or weak vale train in general.

If any of you have info on this motor, I would surely appreciate the input before I start disassembling this motor, thanks to all in advance.
