My car is due for a wof next month. On the last wof my mechanic pointed out some oil leaks and suggested it could be a the head gasket. He suggested a steam clean of the engine to see where the oil is coming from. If it is a head gasket what could the possible repair bill set me back!

Lets go with "rocker cover gasket"and definitely go get a second opinion.

I highly doubt it will be coming from the head gaskets - more than likely a leaking rocker cover gasket or oil filler cap gasket which is a common source of leaks for these engines.

Hi Phillip, What might this gasket cost to repair, at a rough guess. The bottom half of the engine is coated in oil, but I don't have any oil stains in the driveway. The car only travels around 50km per week. Mileage is 166K

Are you sure you don't mean rocker cover gasket! Head gasket would be unlikely but at the same time if it's coated in oil! Rocker cover gasket should only take 10mins. Can't remember the cost of the last gasket I got. I imagine $30ish + labour
Water or steam blast around the areas which are wet with oil. Monitor for a few days to see where the il is from. OR check all levels on a daily basis and after cleaning see the leaks.

Ok this is looking a lot better than I expected. It probably was the rocker cover gasket. Fingers crossed anyway

If it was the head gasket it wouldn't even be going that well, and it would be overheating.
More like a sump gasket, change mechanics.
Google your car, and get underneath of it, and have a look.

Check your water level when vehicle is cold, it would be nearly empty if it was the head gasket.

Wrong, if head gaskets are leaking oil externally they will still run satisfactorily, its only if compression is leaking into a water jacket or water is leaking into the chamber that the running will be affected.This is quite possible if for example like Mitsubishi when your engine designers are dumb enough to put a high pressure oil gallery right in the corner of the block as they did with 4G93 engines.As others have said the correct approach is to steam clean around the affected area and recheck it again after a few days, providing the rocker cover gaskets haven't gone hard and/or are cracking, ie are able to be tightened down a bit further that may sort it IF thats where its coming from.

I don't know, nearly everybody I know who has owned a Legnum seems to have trouble with there car, what are they!, a mechanics dream.

Ok, I'm going to book it in for a steam clean next week. The wof is due on 2/12 so hopefully within a couple of weeks we should be able to see where the leak is coming from. I just hope it is something minor. I trust the mechanic I've been using them for years and they've always been fair

Another thing you could do is to google your manual for your car, it may seem hard to take in, but if you slowly have a read, you get a idea how your vehicle works.

Google is not being my friend. I have been unable to find one. Just a lot of posts on different forums

I have a 6A13 engine manual in PDF form if you want it e-mailed to you.

Yeah, It can take a bit of searching

Out of all the Legnum models to have, the 25ST-R is probably one of the most reliable of the bunch, second only to the 2WD V6 version. There are no turbos to go wrong, no GDI etc and the 2.5L engine is not very stressed and can get along just fine with reasonable fuel economy. I've had four Galants and Legnums with that 2.5L engine and they've all been a dream to own and drive.

and better still is the NZ-new Galant sedan or wagon with the 2.0L non-GDI 4cyl, although it is a little underpowered.

In your book they are a dream, in mine, I wouldn't touch one with a barge poll.

well each to their own. Just saying out that entire range with GDIs, turbos and tiptronic transmissions the best ones to get are the 2.5 non-turbo V6 (in 5spd manual preferably) which hardly anything goes wrong. They were a good enough car in their day but now are showing their age.

oil leak will most probily be rocker gasgets if this is the case the intake plenim chamber will have to removed to do rear one, while this off might be an idea to replace rear plugs to that way you don't have to pay for the manifold to be removed twice. i work at mitsi motors and agree with phillip the 6a13 is a reli strong motor only trouble with it is torque convertor in auto trans

The ones with GDi engines, yes. I've never seen any V6 non turbo Legnums with problems.
