When under load (turbo working) have a noise like a gasket leak,under normal running all seem ok ?
Is it possible that the gasket between the turbo and engine is broken,if so is it a big job to replace ?
Had the Jackeroo for 10 years with no problems,best car I have had,175000 km on clock.
Any advise would be great.

Had the same thing on a patrol turned out to be the gasket between the engine exhaust pipe and the turbo,not a big job.

Also check the pipes (hoses) from the turbo to the intercooler and intercooler to intake manifold. If they become loose or split you will be a similar noise, if you had a boost gauge you would see a lose in boost.

Hi yap yap & g'day Bruce. if the inter cooler has been off the motor and the hose that connects to the turbo has not been put back carefully it will suck air and the more that you accelerate the more it will suck. JUst back the hose clamps off a bit, reseat the hose and tighten them up again. You gave done well if this problem has not arisen in 10 years of ownership.
Cheers,
Kevin.

Hi Kevin, hahahaha it can be come a common problem also when oil happens to get in the turbo from the air intake which is sucked in from the hose which is coming from rocker cover (blow by). The oil will get between the hose and the body making it loose. This happens cause of dirty air filters, oil base filters are not good on a turbo either, and the turbo just wants to suck as much air as it can and basically sucks the oil out through the rocker cover. This was the start of the problems with the 3.0 litre Nissan Patrol motors, sorry have not got time to explain that one to night LOL.

mine made the noise for months before being rectified,no damage,cant comment on yours as i havent seen it,however if it is exhaust gases leaking from the pipe joint it should leave a telltale black soot mark where it is leaking,have you had a good look at it
