Well, looking through the manuals here perkins recomends both 15w40 for temps from -10 to 50 celcius and 20w50 for -5 to 50 degrees so looks like any of the two should be fine. I'll probably go with the 20w50 being that it's an older machine but i'll look into mineral oil since both you guys recomen...

Thanks a lot for the response! Never thought about wheather or not i should be using modern oils, i'll definitelly look into it.

Hi everyone, i have a 1990 3cx with a turbo diesel perkins 4 cylinder (perkins t4.236) and the manual for it recomends 15w-40 for the temperatures i use it in but some people use 20w-50. Any ideas why and what do you guys think is best for it? Would the 20w-50 which is thiker be better for it since ...

Are there not greek companies who take the old turbo from you and rebuild it with new bearings then return your turbo to you rebuilt as a 3rd option? That way you get the good metal inside the turbo, but making the work properly is someone else's problem. I'd rather do this than buy a chinese turbo...

Have you guys heard of this brand JRONE for the new chra???Is it reputable??(https://www.kolos-ms.net/en/item/465/turbocharger-chra-perkins-s2a-311063-chra-311879-1000-070-034-311063-311879.htm) I just looked them up as I've not heard of them, they're a Chinese company, and have a well put together...

I'm nearly sure that is a test button for the dash warning lights. I think if you press it when the engine is going,it's just to show that the bulbs are working. You would need to either remove a fuse or remove the wire from the fuel cut solenoid on the injector pump,to prevent the engine from star...

All good advice here from Slooby and Agrimax Repairing the turbo core is definitely a specialist job. Thoroughly clean the turbo and surrounding area before removing anything. Be sure not to let anything drop into the turbo oil feed when fitting the new core. I have seen the bearings run out in a n...

Thank you guys for the responses, the brand of the chra is JRONE and i've found it for sale from what seems to be a pretty reputable parts dealer in bulgaria. Here's the link, let me know what you think:( https://www.kolos-ms.net/en/item/465/turbocharger-chra-perkins-s2a-311063-chra-311879-1000-070-...

Alright, so after a while i found some time to check both sides of the turbo for oil. Looking inside wasn't relly possible but iused a plastic ziptie and i pushed it carefully through the turbine blades on both sides so see if it would pick up any oil. The ehxaust side seems fine but on the intake s...

I used think "oh its a old engine, It'll be ok to just run it with a oily old turbo" on some vehicles, expecting it just to cause a bit of smoke now and again on affected engines, then one day my Land Rover 90 had its oily turbo go bad, and the engine ran away on the oil pumped into the i...
