Default How to take care of my turbo???

I just got a 1986 Volvo 760 Turbo.Intercooler. Its got 203,600 miles on it. I was told that it was well taken care of and all fluids and tune ups were done at regular intervals. Im looking for any ideas or suggestions on how to keep my turbo in good running order.

-Thanks

I have a petrol 1989 760 estate. It has completed 199400 miles. I regularly change the oil every 2500-3000 miles, oil change that regular will assist your turbo I also top up with slick 50 every oil change.

I do not race the engine from first starting but let the engine warm up about 5-10 mins before I use the turbo. I also always let the engine idle for 2-3 mins after completeing my journey, more after a motorway drive. This will let the oil settle down, if you switch off straight away the there is more chance of oil getting into your turbo.

These really are basic principles for turbo charged cars and will hopefully increase the longevity of your turbo.

All the best
Tom

Please take notice of the heading to this forum which says "NO NEW TOPICS ON THIS FORUM" so that we can close this forum down and use the more specific forums we are now using.

All the best, Peter.

Hi

Have been running turbo's for 16 years, no probs yet touch wood.

Oil is your top priority - keep it clean! Never change oil without changing the filter too. Try to change every 5000 miles maximum, use a modern oil so less sludging will occur, The most a semi-synthetic will cost is 5 more than a mineral oil for 5L and it's well worth the extra for the cold start protection and the general efficiency.

Turbos are beautifully simple but require specialist maintenance because of the miniscule tolerances involved and the speeds they run at - a decent turbo is balanced to about 200,000 rpm. Bearings need to run in nice warm clean oil or they will wear very quickly - when they wear, the shaft can move in and out and the turbine blades can contact the housing, big repair bills. A straight recon with new seals and balancing will cost about 160 or so.

Main rule after the oil is don't bottle it from cold - wait until the guage is at least half way to normal operating temp as cold oil is less viscous - won't feed the turbo to full effect. You can do as Tom says and let it idle for a while, but the easiest way is to drive off-boost (low revs) for the last few miles of your journey so the turbine has a chance to slow down and stop before you switch off. Oil in the turbo is what you want, so don't know what he means there.

Cheers

JG

he's presumably talking about not wanting the oil to carbonise in the bearings of the turbo when it's red hot and circulation ceases, but I guess you've already covered that in your advice.

yes, probably - though less of a risk with the synthetics - ne c'est pas?

Default Oil level.

If you have a low oil level (an oil leak perhaps?), it will kill your turbo. Don't ignore an oil leak. Check level frequently. Don't ask me how I know about this...

And +1 on kinder oil and filter change intervals, and think about oil type and quality!

It will only kill your turbo if its so empty it is killing the redt of the engine too!
Turbos are fed under high pressure, if it isnt getting oil and the feed pipe is good, that means the oil pump isnt feeding anything else either.
Very random thread bump too! 😲😆
