Dissapointing year end with my Roush 427R

PART 2
Well.. I`m Back with and update but not a good one unfortunately.
After haggling with the warranty dept, I fianlly got the to take back the engine for a rebuild. That being said I had to pay for the shipping labour and parts at "cost"..but I would get a 3 month warranty. Once they disassembled the engine the reported "oval cylinders" and confirmed this was not caused by any misuse or abuse on my part... YES my first question was also then it should be under warranty!!..NOPE guess again.

It was recommended to me that the block be replaced along with the rings (kept the pistons).. gaskets etc. All said and done it cost me ANOTHER 4736.50$

I asked that the engine be cleaned and returnes as new.. it came back unpolished and dirty.

I cleaned it and re-installed it. I followed the break in porcedures to a "T" but right out of the gate she was burning oil again. I remained in constant communication with Roush to keep them up to date. I even went as far as sending them a video of the vivid BLUE smoke exiting the pipes on acceleration and when I let off. They did not contest the proof and considering our Canadian climate I kept the engine in and continued to drive it adding oil and gas. I removed it at the end of the season and am ready to ship her back. My dilema is what to do. I dont want this engine back it has a bad omen to it.

Does anyone know why this engine could still be burning oil??? bad intake? seals?? the rings are new... doesn't seem to be compressing in the base... it is burning more oil than before the rebuild. 1/2 pint per tank of gas. I was using the recommend oil weight from Roush 10w30.

Please help, I am getting ready to send the engine back and I would like to hear from any pro engine builders or people who have experience the same trouble. thanks!!!

I can only give you my experience. Mine is a Roush 427SR, it burned quite a bit of oil. I pulled the heads, and had them checked. The valve stems were worn, and could actually see a "lip" at the beginning of the worn area. I had the valves replaced with feria's (sp) that were slightly larger. The heads were cleaned, new valve seats, up put back on the engine, and all is fine, no oil consumption, no smoke when letting off the throttle. Runs really good, and I have no complaints.

Wish you the best of luck on your situation!!!

And here's my update from my 2011 post.
The oil consumption got progressively worse. At 13,500 miles intake gasket let go. After replacement and new valve guides and seals, oil was blowing out the breather and dipstick tube. Piston blowby. Leak down test showed two cylinders excessive. Tore down the engine. Two pistons had small cracks in the ring lands. Lifters worn, cylinders showed no crosshatch. Looked like the engine had 100,000 miles on it. Total rebuild and valve job needed to the tune of $15,000.
After the rebuild and a good dyno tune, runs stronger than it ever did.

Would I ever recommend or buy another Roush product? Nope. This is a total street engine and was maintained meticulously. My feeling is that it should have lasted a little longer. But that's just my opinion.

JHV... ouch... 15k more to redo it? A new one is about 15k. Did you get an HP increase...

I was hoping that Roush would have taken care of the on the first rebuild.. isn't that what a rebuild is for? they are the "experts" on thier engines I thought they would have noticed or tried that. Thanks for the input it will be one of my questions to them when I return it.!

My suggestion? Put it in the back of an airplane, fly over Roush HQ and push that POS out.

But that's just me, I have "issues."

The engine is ready to ship. I will be visiting Roush myself this time! Face to face!!..POS is out.. and the reason why I was put off for so long and ran out of warranty.
