Persistent oil leak in NEO
Ok, so I bought an R34 RB25DE NEO at the beginning of the year, and I knew it had an oil leak, but its really getting to me now, and I'm thinking of engine swapping.
When I bought the car, I cleaned the rocker covers and put some gasket maker on them to stop the leak, which worked for about a week then started leaking again.
A few months later I bought new rocker gaskets from the Nissan Dealership to stop the leak, and spent a day scraping the gasket maker out of everywhere.
A month later the oil warning light came on, so I topped up with oil and tightened the rocker cover to about 12nm to clamp it shut, but a week later the warning light came on.
The crescent seals at the back were solid in place, but there was a lot of oil around them so I forced them out and bought another set of gaskets with the half-moon seals.
Now it's been a month and the warning light is on again, and I can see a leak around the bolts at the rear.
I really want to +T this car, but don't want the oil leak.
I followed the manual saying tighten the gasket to 5.5nm then later tighten to 7.5nm.
I'm really sick of it. The only thing I can do now is to take out the gaskets and put a coating of gasket maker in, but I doubt it would work, and was annoying as hell to scrape off.
I bought all the gaskets at the Nissan dealer and it would take 2 weeks to order more from Australia.
Should I just get a cheap RB20DET?
