Nice clean pistons. What solvent you used in piston soup?

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.

[sms1878]

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.

[sms1878]

parts started to come. today got np242 transfer case overhaul kit.

[sms1878]

cleaning out intake and exhaust housings. doing sanding with dremel nothing much.

will do buffing after cleaning them up all.

I have been thinking about replacing it with 258 's stuff

but for now I wanna put it back all together

[sms1878]

done with the head. painted too.

[sms1878]

got the engine parts too. it is a complete rebuild kit. some parts will be on sale:

i will update the list later.

On sale:
Piston set (std)

[sms1878]

been a while not to update. meanwhile polished around the valve seats before doing the valve seat refacing, neighbor had the tool for that. saved me some money though.

[sms1878]

pics from the valve refacing.

[sms1878]

cleaned up valve springs and rockers so on

[sms1878]

meanwhile bought e300TD with om606.962 engine on it. was cheaper than buying engine separately. has oil leaks around and fuel leaks around fuel pump. not so big deal to fix.
now waits in the yard for next project

Awesome tool! Do you know where I can buy one also? Can you adjust the angel stepless?

It is quite old one from Lisle. I have been searching for it all over the internet but can't really find anything. All I can find is Neway stuff which are pretty pricy for do-it-yourself.

if you are interested in buying check on ebay there are dozens of them but for certain valve sizes. meaning you may need to buy separate one for different valve sizes.

in that sense that Lisle 66000 kit I used is wiser option with multiple blades having different angles.

Attached the picture from its package:

got camshaft bearing installation tool. since fixing engines quite often, it will be useful though.

[sms1878]

after a long break, started to put things together again.

installed camshaft bearings and crankshaft.

[sms1878]

new piston rings and bearings.

[sms1878]

finally finished transfer case. only left rear output crown loose.

painted. changed seals. bearings and chain are OK.

have bearing set left, might keep them as spare parts or sell if anyone interested.

[sms1878]

-valves, stem seals, springs. left the rockers loose for now.
-the timing cam and chain.
-freeze plugs (no pictures)

changed the color of oil pan and timing chain cover

assembled the head and put back the rods so on...

head gasket is from victor reinz. 3 layer one.

[D_Bar]

Looking great!

Wondering if someone would do that to my Jeep... For cheap of course

[sms1878]

finished the assembly in engine. left top cover loose to drop the oil all over before starting.

small things left to make it easy to put back: alternator and servo pump.

painted the pulleys, water pump and the brackets too :P

couldn't take separate pics for everything I guess it is all visible and you understand it anyway. it is a jeep thing
