Hi guys , having some issue with turbos on my 4jg2t , the turbo started screaming when hitting boost like a whistling noise , i installed a new turbo and it did the same on first run (waited 5 min idling before the run) then after 10 minutes it just stopped and was good for afew weeks.
Then this morning i started it up and drove without to much of a warm up and the turbo started screaming and stopped once at operating temp .
The oil drain from turbo has a light split in the pipe but i haven't been to worried because virtually no oil is coming out but its still noticeable , so is it the split in the pipe causing air to drain all the oil from the turbo bearing causing it to scream or is it a case of me just needing to warm it up for longer ? i really dont want to buy ANOTHER turbo.
cheers
