JL Tuotteet 502. bought it from http://www.maspart.com/ps-liuotin-jl...-x-20-ltr.html ( only one is possible to buy )

vinegar and de-greaser. mixed 100ml from each in 20 liter 40 degree water and made couple of rounds with ultrasonic cleaner. dirt was coming off easily mostly with brushing. no sanding.

camshaft is a bit worn. quite normal for 400K engine I guess.

[sms1878]

washed the head. it was too oily didn't wanna get in more mess.
then removed rockers and valves. started cleaning everything up.

still have a lot to go. probably will do light porting in head.
