Fitting a 2.4 engine to a S60R.

Just below

What holds the shim in place? Just the head?

Sorry to hear the bad news..... could it be a result of the recent remap at DNA Tuning or just totally coincidental? But a split liner just a few short weeks after a remap sounds suspicious.

Possibly the result of the remap, but not DNAs fault, just an inherent problem with the 2.5s.

[stephenevans99]

I believe so.....it's like a plague on the ST Owners Club. But those boys tend to go for the aggressive maps..

The shimming is a push fit in the block, so as the engine gets hot it grips the shimming

Was there any running signs when this happened

it dosnt just happen on mapped cars. lots of standard ones crack to. id says its being going for quiet acwhile

It's recently started overheating, but I believe water loss is a typical sign, which we haven't had.

Had the car in to the garage today to have the thermostat changed because it's overheating, to be told it'sn got a cracked liner. (Awaits the "I told you so" posts) The plan now is to fit a 2.4 lump, but have a couple of questions.

1. Does the 2.4 engine have VVT on both cams, or will the heads have to be swapped over?
2. Is the turbo oil return in the same place as on the R?

That sucks mate sorry to hear it

[Biff]

Trust me mate, its not that hard. Bad times its got to come apart, time consuming but its possible.
Good luck with it, its just the labour that's expensive the job itself is sound really. As Colin said some stainless will do & I'd be tempted to do them all & enjoy the raised rev limit a bit more!

[graemewelch]

if you did do the job your self the hardest bit will be stting the vvc when the belt is refited, whats the milage on your car

Hmmm, interesting, might do this to my 2.4 engine which is waiting completion.

Don't get how shimming would fix a cracked liner though, wouldn't the sheer forces involved still find a way through? And what about the reason why the slit is there in the first place?

Im having mine shimmed I hope next year from tim

[Dream3r]

I take it they've has a scope down it? All the others I've read about monstered coolant, or at least sipped it.

Best thing you can do mate. You'll be able to hit the train to Tim's and back as well, East Coast with one switch.

When the engine is cold the crack closes rigth up but when the engine is at normal running temp the crack opens up,

So shimming the block stops the crack from opening up.

Yeah I know. I think its inevitable that all r engines will fail like this at some point

Shimming the liners does not fix a crack, but it will stop them splitting in the future.
I believe the splitting is caused by the flexing in gap between the liners this small amount of flexing allows the liners to spit over time, and If I am not mistaken others have also called it trumpeting in the past as well, which is a result of to much pressure in the cylinder at the point where everything ignites and again the pressure has to go some where!
Shimming your block will help with both of these!

The days of people fitting the 2.4 due to liners is over!
Loads of people on T5D5 have had their 2.5 blocks shimmed for a long time with heavy modification and no problems!
I would stick with the 2.5 as there is no replacement for displacement as they say!
