Hi...I'm new to this forum, as I'm not currently an owner, but I'm in the market for a full-size Montero, 94-97.

My question is this...I'm aware of the oil consumption characteristic of the Montero, but I can't seem to find agreement of exactly what the CAUSE is. I've spoken with 3 Service Advisers from different dealers and read owners reviews online. Some say the 3.0 is more affected, some say the 3.5. Some think it's the valve guides slipping out of place, others say it's deteriorating valve stem seals.

Please, which is it?...and which motor is more affected?

Also, I'd like to know if there are any other specific issues that I should look out for in these vehicles. Any knowledgable advise is welcome!

Thanx in advance...Paul

I owned a '95 Montero, 3.0 for 151,000 miles and now have a 2002 with the 3.5. I noticed oil consumption issues after about 75,000 miles. I never had the engine torn down to see what the problem was so what follows is opinion. There are two conditions under which I noticed active smoke from the tailpipe; start-up and after a long idle. Those two conditions led me to believe it was the valve guides that caused the problem. I used a quart of oil about every 750 miles. Late in the life of the '95 I began to use an oil treatment from Lucas Oil that reduced consumption but I discovered the best way for me to deal with this was Valvoline Instant Oil Change. They give free top offs between changes. That was a lot cheaper than tearing down the engine.

Hey, thanx Moontero for the insight! If I can't get to the bottom of this I just may need to take little bit of bitter with a lot of sweet!!!
