XC90 LPG Damage?

sutherland · Mar 28th, 2009, 23:03

I've posted a thread in the XC90 forum about possible damage to a 2.5T. If anyone here has any knowledge of this I'd be grateful for your responses: http://www.volvoforums.org.uk/showthread.php?t=69406

Been thinking about changing my chariot (a 97 V70 2.5 10V, 180,000 up with 130,000 of that on LPG) and went to my trusted LPG fitter to ask his advice on taking the LPG from mine to another car.

His advice? - Don't bother with a Ford-era Volvo, and don't try to LPG a turbo-charged car - you'll get valve seat recession!

Cheers

There can be problems with valves and valve seat wear on the ford/volvo engines but the old volvo engines were all fine. The valve and seat material were changed by ford and it is only since these changes that there have been problems.
As to turbo cars there is no issues converting them to LPG.

An LPG conversion is fine to do on the newer volvo's but you would suggest using flashlube or be prepared to have head work done.

Do you know what year the valve seats started to become a problem?

I understand that valve seat wear becomes an issue from the time of the introduction of the later phase 2 V70s, and the merger with Ford so MY 2002 onwards?

It isn't insoluble, and a flash lube system can be fitted, but this of course adds cost and complexity.

Cheers

Mine's an 2004 XC90 T6 (engine number 3428427) any idea which engine I have please the older or the newer?

There is a fair chance that engine will have the softer valve seats and therefore need a valve saver system to protect the valves.

There is another possibility that has not been explored as yet with Volvo engines but has been done with Subara.

The Impreza engine has hydraulic lifters as where the forester has solid lifters. The Forester is known to suffer with VSR but some LPG installers are changing them to hydrolic lifters and this so far has been successful in eliminating costly cylinder head repairs without the use of any oiler system. I would be keen to try this with the volvo/ford engine. I'm sure we would be seeing the same results as other dealers have with Subaru.

As to the T6 you have if you are wanting to convert the car I would recommend changing the lifters, but if you do not want to do that get a valve saver system fitted just in case. Either of the above methods should ensure the integrity of the valves and seats.

With the power output of the T6 you will need to make sure that you use a good installer and good quality equipment.

Associated with our business is a very well established and expereinced LPG business, we generally get to sort out other peoples problems.
Volvos convert exceptionally well adn theres no problem with turbo engines, however the cost of swapping a kit from one high mileage car to another isnt generally viable (its almost twice the labour after all)

A reputable company will give you a straight answer as to whether its suitable for your car or not - after all they have to guarantee their work AND maintain their reputation - pick someone who has been around a while

I have from 2003 my 2.5T and often considered LPG but each time I have checked I been told by reputable LPG conversions companies that it is not advisable on from 2003 on which fits in with previous replies.

I now have a XC90 V8 4.4 so LPG on this would be nice but I think for same reason it is not a good idea.
