FFRE Stage 3 Short Block - feedback needed

[robvas]

I'd find a new tuner for engine #3. Guys make stock gen 2 engines hold that much power.

This is the full diag from the shop -


Diag: customer reports picking up excessive knock. Upon initial inspection we found a blown headgasket with significant coolant in cylinder 4 and 5.

Tear down: excessive amounts of oil found in intake manifold and intake ports of cylinder heads. Upon removal of cylinder heads we found multiple spark plugs with the ground strap bent and touching the electrode. Likely cause is detonation from combustion of oil in the cylinder

Inspection: Heavy scoring on cylinder walls. Severe discoloration of cylinder walls. Due to the nature of the plasma transfer wire arc cylinder liners, block can not be machined for fresh cylinder walls. Appears that the oil rings on the pistons have failed causing excessive oil in the cylinders.

Conclusion: recommend a new sleeved block.

I'm just saying, you didn't hurt a piston or rod, upgrading to a FFRE isn't going to fix anything that isn't broken.

Please see latest detailed diagnosis from shop in most recent post. Looks like piston ring failure

Since they already tore it down, you could have the Aluminator Sleeved, no?

Cylinder walls are jacked up - something about the the aluminator and the cylinder liners wont allow it to? Looking for some help here on if anyone has sleeved an aluminator block.

Without being too mechanically proficient, im sure someone here can shed some light. All i know is this shit sucks

Aluminator uses the same engine block as the regular GT

In for the learning…but at first blush, I’m with the group, doesn’t sound like another block is gonna solve your issue

Lol everyone is saying that....does it all come back to the tune without seeing data - couple motors with 2 very different issues. Two different tuners on each one. One motor with bearing problems which the motor ate and spat out, the second with piston ring failure. Is timing the culprit? Is my harsh driving the issue? What can I do to avoid engine failure on this next one....

The aluminator has the same cylinder walls as a stock GT engine. They just replace the pistons and rods. So if you can sleeve a new block from Ford, you can also sleeve the current block you have (unless it's cracked somewhere else and beyond repair). But the sleeve situation has nothing to do with its ability to be sleeved.

Thank you - not sure why the shop would go against sleeving it (they would be making money to do it) unless the block is super effed up. I have yet to see it but will be picking it up/ keeping it as a spare if not all too damaged.

I wonder if it would be worth testing a sample of the e85 you've been using.

I use VP Fuels C85 by the pail....this motor has never seen pump anything

Gen 1 and 2 have traditional pressed in sleeves, the gen 3 and 4 have the plasma wire arc spray in sleeves and the aluminators use the same block as the production engines. The shop may have been confused but if OP has a gen 2 aluminator like his profile says he does, they can be resleeved.

The OP did not specify where the crack is, if its in a cylinder wall, he can just resleeve it. But if its some where besides the cylinder wall, he needs a new block.

My recommendation, fix or replace the block and transfer his old parts over, replace the bearings and rings and use ARP head studs for maximum clamping force. And find a new tuner.

Gotcha, sorry didn't know what C85 was.
