So i tore this cunt apart today..... Still didn't pinpoint the actual problem but got a good look at just about everything. No metal shavings, light pitting on piston 3. Ringlands all good. Rings good. Pistons slap like fuck. Some weird wear patterns on the bearings but no shavings so whatever. Lets reuse all that shit.
Anyway, less bullshit and onto the pictures and half asleep/inebriated video commentary towards the end.
Clutch looked really good. Some glazing from learning how to not stall (60 second learning curve over stock clutch) probably.
Threw her on the stand yesterday after work.
Started teardown today.
Clean under the covers.
You can also only go so high on the lift with the cams due to them sliding into the cylinder head instead of bolting down with caps. It's alright. With 270's i think power falls off close to 7k and that's on stock ports with no mention of which intake verbatim from some shit i heard someone say somewhere. These are NOT rev happy motors. Get something else or spend $3000 extra if you want to rev higher than 7k with more than a half inch of lift. Who needs that much lift?
Oil drain flopped down after i drained the oil already and pissed a nice puddle. Whatever. Lets pull the heads.
Filthy but wiped clean without issue. Bores were ok. No cracks in the water jacket. It rained and filled that cylinder with water while the motor was sitting on a tire in a driveway under a holy tarp with the plugs removed. Dont be alarmed.
Head gaskets are FINE. Middle finger pointing between 5 and 3. My suspect blowout. Was disappointed yet happy at the same time. I can PROBABLY get away with re-using them too! Lol. Heads came clean off the block as expected.
Here's the area where i found pitting/signs of det on cylinder 3. Camera didn't pick it up. I pulled all six slugs since 3 and 5 were low on compression according to the dry comp test.
All bearings look like this. Crank looks fine.
Lets go digging some more! Fucking cunt motor is cunt.
As i figured, we'll do the copper headgasket spray on new head gaskets. I'll replace the cam seals again and the front main again even though they might not need it.
My last turbo was fucked up when i got it. My new turbo has a little bit of end play. I was hoping i could get by with idle and light revs but nope. Will just rebuild it. No big deal.
Clawing your way through a brick wall is HARD.
