Smoking L28

Post by JelmerMQ »

My L28 is smoking when I loose the gas. It also smokes when I make a lot of rpm's. Do I need to replace my valve seals?

I had the same issue with my L28 a year ago, and then it had a leaking head gasket. They replaced vavles and guides when they did the gasket and that has fixed my smoke problem.

But it might be cheaper to buy a 2nd hand engine than getting your rebuilt. Yoiu might be able to get 3 or 4 of them if you're lucky :)

smoke

Post by rockrover »

What colour is the smoke? if its black check your float level in the carby and if its blue its more than likely rings and if its only when u start or idle for a while it is probably valve stem seals...i have had the float problem just recently and now have had it fixed

it's blue. I don't have the standard carb anymore so it isn't my carburator.
I know that when Nissan FJ20 engines smoke, the valve seals are worn out.
