5 GT Turbo Removing liners with engine on the car - advise needed

[itzik]

Hi,

I found a water leak from the liner seal on cylinder number 2, I would like to remove the liner with the piston inside and replace the o ring seal, is it possible? Any other advise?

Pictures of the leaking seal attached.
TIA

Head & sump off job to remove

I think you can do it with a cut down piston ring compressor, it's been done on a 21 Turbo for sure so I don't see why it couldnt be done on a 5. As long as you can get a ring compressor under the liner and then slide it out after it should work.

Sump removed already to replace the oil pump, then I found this.

Head will be removed to be replaced with a new head, I was thinking on un bolt the pistons connecting rods from the crankshaft and then use a wood to knock the liner out (with the head removed), is it possible?

I guess on this method I must remove the cranckshaft, correct?

Take the sump off and pull the piston and liner out. I personally would just pull the engine out, leaving gearbox fitted

Can I pull the liner out with the piston and connecting rod inside the liner? I want to avoid having to pull out the piston from the liner.

Yes

No problem to pop the liner with piston, just make sure that you put a mark on the piston so that it goes back in the right way round! Check the seal areas for corrosion! If there is pitting you can repair using materials such as Belzona 1111. Make sure also that you have the correct coolant in as these engines are prone to corrosion due to the mismatch of materials, a quality inhibitor is essential in the coolant and should be changed regularly as it depletes.

Yes pull the liner out complete with piston, easy job with sump off.

Thank you everyone, this is great help, I just purchased new seals they are surprisingly thin...

I will go ahead and do the job, everything is noted.

One more question,

What's the proper way to mount the rubber o ring? do I slide it in on the liner all the way to the top where the wider diameter starts?

 

[DaveL485]

Yes the seal sits on the ridge around the liner.

Thank you Dave.
