1965 Mustang, Ford Performance 1996 5.0L HO Crate Short Block with the stock '65 289 heads. Engine was assembled & installed by a Mustang Specialty Shop in '97.
Customer complaint.....Engine uses large amounts of oil, A quart per 100 miles if he's lucky. While it got real bad in the last year.....He said it always used a lot of oil. Engine has @ 7,300 miles on it
Pulled the engine Wednesday, Spent Friday & Today on disassembly, Inspection, Cleaning & I have the Rotating Assembly back together.
What a mess.....
*Fuel Pump Eccentric is rubbing on the Timing Cover. They used the '65 Eccentric which is too wide for use with later model Cam Gears. The Timing Cover is just about rotted out....I'm sure it didn't look much better 26 years ago?, probably why they used a whole tube of RTV?
*Valve Guide seals had hardened & roughly half are split in 2, Otherwise the heads are in great shape.....New valve seats, Valves, Guides, And they're flat. I'm gonna clean them up, Lap the Valves & Install new Seals
*Short Block is also in great shape for having a bunch of Aluminum ground into the oil, I could see some of it embedded in the Bearings, But the Crank looks new & I see no need to have it polished.
*ALL 16 Oil Control rings were installed with the gaps lined up!! The Compression ring gaps were also lined up on most of the pistons

*Every gasket was smeared with RTV on both sides, I've never seen so much RTV used on a engine in my career! Of coarse the Oil Pick-up was packed with RTV, He must not run this car hard as I would've expected some beat-up/spun Rod Bearings with as loaded as the Pick-up was??
My Machinist is months behind, But he let me come over after hours & Hone the Cylinders on his machine, Just enough to get the correct wall finish.
Everything measured well within spec, It's getting new Rod/Main/Cam Bearings, Rings, & Timing Set.....The Cam Gear has quite a bit of wear, I assume this is because it was in a bind with the timing cover?
How do you not notice the engine got 10 times harder to bar over after the Timing Cover installed?
