Default LIM Torque spec'*

I have a VIN 1 Series 1 motor that we just changed the LIM gaskets on
Would like to confirm the techinfo specs
91-99 (except 95-97 Vin 1 and K).......89 (In/Lbs, twice, in sequence)
Can someone confirm please that this is the correct torque for my motor?
Thanks

IIRC I torqued mine to 11 ft/lb. I honestly can't remember where I found 11, but after seeing 89 in/lbs I thought that was incorrect, and I did 11. Maybe someone else will give a definitive answer.

89 in/lb is between 7 and 8 ft/lbs. (closer to 7)

132 in/lbs is 11 ft/lb.

I don't see why a 95 VIN 1 would be different than a 94, it'* the same motor.

I believe Bill told me 11 as well.

Roadrunner, if it were me I'd do 11 ft/lbs. You wont kill the gaskets going 3 lbs over (if 89 in/lb was correct), but that'* just me.

Valve cover bolts were incorrect at one point and have been changed.

11 Ft Lbs will be fine... Make sure you use some medium grade thread locker to keep the bolts from backing out

Default More questions Oil Filter adapter gasket and leak down test

I have bought a 1995 Riviera Vin 1 series 1 to put in my Bonny
One thing I noticed is the Engine Oil cooler lines off the adapter are not on the Riviera mtr
I need to transfer the adapter from my motor to the Riviera but cannot find the gasket listed as a separate part number.
Can I just fab one up out of gasket material? You know old school farmer make it if you can't find it?
Second thing is we did a leak down test on the Riviera motor before we did anything to it. The input to the test was at 80 lbs on the compressor tank. cylinder #2 and cylinder #3 had moderate leakage. Rest of cylinders where in the good reading range.
#2 was sounding like a leak on the exhaust valve and could feel air movement on exhaust header and cylinder #3 on the intake as we could feel air movement on the intake.
I am thinking just dirt in the valves that should clear out once we get it running or sticky lifters that should free up once we put some oil in it and get it warmed up.
We looked at the bottom end and still see crosshatching on the cylinder walls so feel the engine has not been abused to badly. Short of pulling the heads and getting a look at the valves (Head gaskets are 59.00 each here any thoughts?
This car has cost me a small fortune now!

Wrong engine, Macdrive. Spces aren't the same for an L67 Series 1. Please be very specific when posting specs like this. You are misleading people.
