1988F Volvo 760 GLE 2.8i V6 - Belt Or Chain?

Yes it was , and also in many other cars .
It was jointly developed by Volvo , Renault and Peugeot so appeared in many of their cars in lots of different guises the latest form had 4 valve heads after volvo ditched in favour of their own B6304F . Volvo always had the most powerful versions though .
It was available in 2500 cc turbocharged form in the Renault Alpine GTA .
It was never a V8 although in the design stage it was going to be , then the fuel crisis of the 70's came along and they settled for a V6 , hence the unequal firing interval which was fixed in 1988 by modifying the crankshaft crankpin spacing .
The 760 GLE auto was one of the fastest accellerating cars in the world from 30 - 50 mph ... 2.9 seconds , look it up , faster than a V12 jag in this speed range :-)

some confusion above with chains / belts , the V6 has 3 chains , the 760 turbo is NOT the V6 it is the volvo 4 cylinder so DOES have a belt ..

Not exactly, the DeLorean had the earlier 'odd-fire' version of that engine equivalent to the B28 but in a detuned form. A popular upgrade for DL owners is to fit the B28E's inlet manifold and fuel distributor as it gains them an extra 30hp!

The B27/28/280 has timing chains, one per bank and one for the oil pump. There's no set interval for changing them, but keep an eye on the tension in them and change the tensioners or belt if serious slack appears. The general consensus is that the chains will last for 250,000 miles before any issues arise.

The V6 always had a chain, they certainly did not last longer than a belt in the early B27, I recall changing chains and severely worn sprockets at 100k miles, poor oil feed was the problem, this was improved in the B28 and nearly cured in the B280.
In fact the B280E was a pretty good lump, no competition though for a B230ET or B230GT in the 760 (GT was the lambda sensor in the exhaust manifold for the electronic system but still using 98 ron leaded, replaced by the FT with the 95 ron unleaded)

Thanks everyone for all your help.

Your all a 'knowledge bank' and all very useful!

Thanks again

The engine used in the Volvo 760 (V6) was child of the joint venture between Peugeot, Renault and Volvo (known as the PRV engine).

It did not have 2 cylinders"lopped off"for Europe. And it was used in the DeLorean.

Biggest issue with chains is over time they stretch and often the tensioners fail before the chain does - often with the same results (engine = grenade).

All Redblocks (4 cylinder engines) have belts.

No, but as Clan says it was meant to be a 3.5l V8 hence the 90* bank angle. The 1970's oil crisis and the fact that a Renault altered their previously agreed 30's design meaning a V8 would no longer fit under the bonnet meant it was changed to a V6.

They kept the unequal firing intervals too until 1988 when the crankshaft was changed and the engine became much smoother . Pity that volvo ditched the engine before the 4 valve heads came ...
