Piston rings gone.

[Furio-92]

My piston rings need replacing, Any one point me in the right direction for some? Its for a MK2 VTR, Also cammed if that makes any difference, Thanks guys

[Bedford126]

wouldn't bother just get another vtr engine and swap the cams over. save a hell of a lot of time and money.

[stevo67]

As above vtr engine are cheap these days & it would be more cost effective to just to fit a lower mileage engine.

[Gandi699]

you 100% sure its rings and not stem seals?

[RustySkull]

What makes you think it's the rings?

[blackie_2k5]

Defo not worth replacing rings mate

[jeffchiz]

yay welcome to the club mine are on there way out, should be getting a new bottom end at FCS which i will get re built then spend a day swapping the bottom ends over :)

but i also could be pointed in the direction of where you can buy them from? ill probs jsut get them throug pug1off but would like to compare prices from different places

[RustySkull]

First of all if you are buying new rings you need to know the size of your Pistons. 78.5mm is standard size but I bet your bore has worn.

Also, if you don't know 100% it is the rings you could replace them and not fix the problem.

[saxo-parts]

get ours from lindley engineering in nottingham

[Furio-92]

Cheapish engines then? anyone? :P

[jeffchiz]

Cheapish engines then? anyone? :P

you dont have to follow everyone advise and buy a new engine, can be done quite cheap if you do it yourself, as i said im picking up and rebuilding a bottom end (with help from my mate), and should only take a day to swap bottom ends over and then you know your bottom end rings/bearings/bolts/headgasket are all good, also a good time to do a cambelt change, then you know your engine is in good working order, depends what means more to you spending more making your engine like new again or risk buying another engine which could go bang

however it is different for me as it'll probably be cheaper/be a similar price for me to refurb my 16v than buy another one

[RustySkull]

Yeah I wouldn't but a new engine, but I'd defo check it is the rings causing you problems.

What is happening to make you think it is the rings that are the problem?

Was that question aimed at me or him? Lol

Oh sorry mate, OP lol.

Although, you also if you think you need advise lol.

[jeffchiz]

It's quite obvious for me tbh, before the car was mappped it was stupidly over fueling and now my oil catch tank fills up very quickly, my car is giving itself an oil change every few weeks lol its obvious that the excess petrol has damaged the rings and now the oil is pressurising and coming out where ever it can lol

Oooo lol, are you sure your crank breather isn't blocked?

Just a suggestion as my VTR had what you have and it was a breather blockage :)

Which one is the crank breather mate? Can't think of where that is :s

[jeffchiz]

Is the pipe that runs around the head in to the sump?

[RustySkull]

Check that, check the rocker breather also.

What you described can be caused by bad rings but breather problems will cause pressure and blow oil out the dip stick, and any other hole that it can get out of lol. My catch tank used to over fill like every other day ahaa.

[jeffchiz]

I'm guessing the rocker breather is fine as that is where the catch tank is fitted to so it wouldn't fill up with oil if it was blocked? I'll see about checking the crank breather cheers

Ye lol, just thought I'd say incase you had some odd set up...

If you're gona change the rings you might as well get some new Pistons!!

Ha you think I haven't thought about it! It's just gonna be a cheapo rebuild, however ill keep hold of my old bottom end and build it up when I can aford it with the pistons/rods from pug1off, get the crank/flywheel lightened and a set of 812 catcams I think they are should see me with 190bhp+ :-)

[RustySkull]

Ahaa sweet mate.

Did you check the breather that is next to the dip stick and goes into the side of the head?

[Furio-92]

The car stinks of oil when its on, throws out blue smoke in the higher revs

That could be valve stem seals or head gasket, it's more likely to be either of those than the rings really...

Is that the only thing that makes you think it's the rings?
