The piston could take no more and my SRT4 is getting a fresh shortblock. Number 2 cylinder had zero compression while 1,3,& 4 pumped 170, 167, & 155. Teardown so far shows no deposits on the back of the intake valves, bearings look like new, crankshaft looks like it just went in. Both cans are perfect save for the one lobe on the exhaust cam which has a small groove in it, yet the roller on the rocker is fine. The bores are worn, but cross hatch is still visible. Piston skirt coating is gone in some places, but 70% of it remains. #2 is toast & the rod is bent. I suspect the oil consumption lead to the fair amount of carbon build up on the faces of the valves and combustion chambers, which in turn caused the detonation and damage.
The head and intake I have been working on will be put on a J&E piston attached to Eagle rods in the shortblock. The same turbo and all other components will go back in the car to evaluate the dynamics of the head & intake.
More to come later, including some pictures.

253k is a pretty damn good run!

[glhs727]

yea 250K+ is awesome considering none of the kids around here can make their srt-4 motors last more than 90K
Maybe Steve should give them lessons on proper vehicle maintainance and care...

I think you got your moneys worth out of that engine. That's probably one of the highest mileage SRT's out there.

+1 nicely done! Sounds like it could go a bit forther if it wasn't for the one cylinder...

LOL true story!

Steve, post your story on SRTForums and give us a link so we can watch the idiocracy

My engine has 50k on it now. I really would like to make it to 250k, but that will take 100 years at my current rate of mileage.

I thought I was doing good at 53,000 miles. Did you have to replace any suspension parts in your 253,000 miles?

[Keito]

At the rate I'm going I won't have 250,000 before I die.

I keep telling people you can drive them hard and not beat them. Taking care of the car is paramount.

I have to agree! I should have exercised more restraint and had it go longer yet.

The only suspension components that failed were the struts. I put inverted BC coilovers on it. The sway bars were changed out of desire as were control ARM bushings, although the horizontal bushings were almost toast when changed.

Get out there and drive! My SRT was over 200,000 in under three years of ownership as I used it for the courier work I used to do. The last 3 years it has been "resting" by comparison.

OUCH!

Well, them rings are still usable, LOL

[roachjuice]

Jb weld it back together.

[black86glhs]

I see your problem there.

[BadFastGTC]

Too weak Mr. Strong.

Jb weld it back together.

[BadFastGTC]

The new motor is in the car and once we checked it over for leaks, I drove it home. The combo seems very nice so far, although I exercised self restraint and kept my foot light on the throttle. Here are a few more shots of the new engine and parts. The oil pan was powder coated the same color as the intake manifold & valve cover.

Was that hole machined round again was it out much?
whats the advantage of the domed piston over the flat top?
