Title: High mileage
Post by: maddix0193 on 18 October 2009, 11:31
quick question. what kind of mileage is a 16 valver gonna hold out till?? have never seen any go past the 200k mark. just wondered if its worth tarting up a car with 157k on the clock?? :undecided:

my mk2 16v drove to the scrap yard with 215k on the clock. you can't kill em as long as they get looked after. keep it and look after it. usually around the 160 mark you can expect to be changing valve stem oil seals and stuff like that. my mk3 16v has 168 on the clock and still going strong.

Matt off club gti's mk3 16v had done 181k when I last saw him at the clubgti rr day and it put out 175bhp. I know he still has it, so he must be close to the big 200.

Service it regularly, and look after it and the engine will keep going and going! I'd be more worried about rust or the gearbox than the block!

My 8v has done just over 130k, it has only lost about 5bhp from the factory spec.

mine had done just under 130k when it was on the dyno back in march and it produced 1 more hp than factory, and that was with no mods at all, totally standard.

Valve stem oil seals are little rubber or neoprene seals in a metal case that fit on the valve stem, and against the valve guide thus preventing oil from being sucked down the guide and either into the intake tract and into the combustion chamber, or into the exhaust and being burnt, producing a smoky exhaust, especially when hitting the throttle after a long overun, like coming down a long steep hill with the throttle shut.
                         Changing them means taking the head off, and removing the valves.......... not a hellishly hard job, if you know whats what. I've done cars in my drive in the past.....nice weather, lots of tea, plenty of time.......lovely..... :wink:

if you have the right tools to do it you don't have to remove the head but its a pain in the arse. i'd personally remove the head and while you're at it replace tappets and all gaskets and seals on the top end for peace of mind. i can send you screen shots from elsawin on how to do it and all the torque details for all the bolts etc.

id just leave the head on, you can do valve seals and cam followers as long as you can hold the valves shut using a commpressor/the magic rope trick. Will save alot of time + head gaskets+ bolts arent free :drool:

not everyone has access to a compressor though and it's still gonna cost a few quid if you don't have all the tools.
