Wow...... That's impressive sir... I've yet to have one give me problems taking it out with the tool it takes longer to set the tool up then to remove the sleeve with it haha...

I did have one the other day where the trans side was stripped out... Kinda sucked to tell the customer that :( she traded itin on a new xc60 tho

I can't believe it will stay so stock though......

I don't understand.. That's what everyone says.. :huh:

:)

I have ordered a JR filter element like used in my former S60R.

Also it looks like the TCV has had it's best time.

Not sure about lowering yet. The shocks are all still OK but rusty on the outside. I'm afraid that when I lower the car now it might wreck the shock seals. As you may know the Monroe shocks aren't cheap..

New tire arrived this morning. Will pick up the wheel later today.

Think I will leave the car as is for the time being and concentrate on other long overdue projects.

Took the 2.5T engine I bought for the carrier apart for overhaul,

Engine look pretty good inside given it has done 168K miles. Next week the parts will go in the washer and maybe a slight hone. Valve seats are being checked and rebuild using all new seals. Thinking about using a 14T turbo with this engine. All other completely OEM 2.5T including M4.4 LPT ECU.

Also fabricated an adapter plate for adding a Drenth 6 speed sequential box to a Toyota 3SGE engine. A project of a friend. Engine goes in to an AE86 Rally car. We received a dummy gearbox from the manufacturer for fitment. Turned out nice IMO,

This gearbox uses a Getrag 265 bolt pattern. As you may recall I made an adapter plate for this box behind a 5 cylinder a while ago,

The Drenth box also fits but the adapter plate was made for a straight up placement of the engine. While machining the Toyota plate and having the dummy box available I took the opportunity to fabricate another adapter plate for fitment to a tilted engine.

You never know... ;)

Johann...

I know there has been talk of the cylinder walls on the 2.5T motors being thin and having issues but I can't seem to believe it since it must me a very small difference

Any way you know the differences on the 2.3, 2.4, and 2.5 cylinder walls?

Kevin,

Hasn't there been plenty of discussion about this issue? ;)

The 2.0, 2.3 and B5244T5 use an 81 mm bore. The latter also the stroker crank.

All others use a 83 mm bore.

There simply is less material for the larger bore engine's which translates to less strength. I think the biggest issue with the older engine's is the way they are produced. Somehow there isn't a good heat transfer between the metal sleeve and the aluminium casting. This way the heat isn't transferred evenly to the cooling chamber resulting in hot areas in the material which eventually cause it to crack. If you are lucky you have a good engine which doesn't crack but when you open up the engine, 83 bore, after considerable mileage you can see or measure that the cylinder has been "blown up" at the thinner places. Thinnest part is near the slit where it can be measured that the cylinder wall has been pushed outward over time.

There are plenty of high HP big bore engine's which do well but reality shows that compared to the 81 mm bore engine's these engine will develop cracks sooner.

If you take a look at the evolution of the 5 cylinder engine over the years it can be noticed that cooling has been the biggest issue with this engine. So many little and big changes have been made ranging from flow changes to a completely different cooling setup for the last R engine and newer RNC engine's. Also the casting process has been changed to improve the bonding of the sleeves to the aluminium.

That really sucks. Are they new wheels you purchased, or did they come with the S60?

I bought them new in 2005 or 2006. Also have been used on several car as winter rims and I loaned the rims to a person for 6 months or so.

I found the problem, the valve has a small leak which apparently only started opening when the rim got warm...

Unfortunately second new tire is also shot. :(
