Dissapointing year end with my Roush 427R

[james911pro]

@Varmit, there is another post on here where a guy had a 402 and even after it was rebuilt it still consumed oil way beyond normal limits and Roush replaced the whole thing at their expense with a 427R.... I am going to contact him to see who he spoke to! Mark at Roush told me to try Rotella-T 15w40. apparently (after doing some research on the net and with an engine shop) there is a special additive in it that counteracts the oil burning.

We are the dealer who installed and serviced that 402 under warranty and it was within the first year of the 2 year warranty and all procedures for reporting/documenting the issue were followed.

It should be noted the Roush warranty begins 6 months after the engine is shipped unless you send in the warranty card sooner. We have never inventoried a Roush engine for this reason.

The Roush warranty was rewritten in February 2011 so it is no longer as extensive as the past. I still feel it is among the best, it just became a little tighter and you have to be a lot more proactive in the documentation.

Thanks mucho
will try that, It went through a qt in 150 miles. Blew me away, Not hard driving either, could kind of understand if it had been hammered pretty hard, but nothing close to it!!!!!!!!!!!!!! Scary.

Varmit-forget the Rotella-T. "Mark has told James a fable.
There is nothing in any oil to 'counteract' oil consumption. Especially what you've got-1 qt/150 miles. Even cement wouldn't stop that.
Instead call Mark and ask if Roush is using 'low-tension' rings on the pistons. And ask what the piston to wall and valve guide clearances are. The motor obviously has too much clearance machined in.

Kind of what I'm afraid of, but there is no smoke or anything coming out the pipes
want to do a compression test and leakdown
