Tappet failure

[ColoDisco]

Already checked rockers. Was hoping one of those was the problem so it would be a easy fix.

Midday update:

Secured the AC condenser to the hood with a bungee. You do not need to evacuate the system as you only need to move it up about 6 inches.

Cam removed:

Cam lobe worn down. This is the same lobe as the bad lifter.

Cleaned up the gasket surface for the timing cover and lubed and installed new cam. Used the break in lube that came with the cam and lifters. The new cam is not machined to allow the retaining plate but per the tech blog it is not necessary. My cover has the stop built into it.

Used the same break in lube on the contact surfaces of the lifters/tappets. installed accordingly.

Attached gears one at a time and set timing marks. Removed them and set them in the chain so the matching marks aligned. Slid gears and chain on.

For this afternoon continue assembly.

Not much progress this afternoon. Went looking for VR1 10w something and failed. Did manage to clean the timing cover and install the spacer, distributor drive gear and torque down the bolt. No pics of this.

Update on oil. This is directly from mark at D&D for his cam kit.
In the kit I have a bottle of crane cam super lube break in concentrate. 99003-1
He recommended castrol gtx 10w-30 with the additive.
If at all possible attach a oil pressure gauge to the system during break in to ensure you are not dry firing the engine.
Start the engine and rev to 2000-2500 RPM for 20-25 min. After the initial break in continue to let the engine run (called run in) adjusting from idle for a while to 2000 rpm over the next hour, shut off the engine. While engine is still warm drain the oil and remove the filter, this drains out the assembly lube.
Refill oil and replace the oil filter add another super lube (mark recommends adding this on every oil change) and continue on with normal maintenance.

I have to say Mark at D&D has been a Huge help. This is a daunting task, basically open heart surgery for your engine. If you take your time and follow the steps anyone can do this.

Very productive day today!
Started by finishing up cleaning the timing cover. Removed the crank seal and installed the new one. fished cleaning up the cover for the new gasket. Installed and torqued the bolts down.
Installed the rockers using white lithium grease per Mark at D&D.
Installed the crank pulley, using the same wood method torqued the crank bolt down.
Checked timing then installed the distributor making sure it is in the same location when I removed it.

Rockers installed, also installed the valley pan gasket.

Sorry for the blurry image. I cleaned and installed a new gasket on the oil pick up tube. Also installed the oil pan with new gasket and cleaned and installed the torque converter cover plate.

Really just have the intake, viscous fan and radiator left.

Not sure anyone is reading this but I will continue updating. Hope this helps someone someday!

Hey I'm reading this and it will be helpful some day. So thanks for posting the pics and write up! Keep it coming!!

Excellent! That is what I was hoping for!

May not finish tomorrow. Have possible snow here tomorrow, and I am doing this in a carport not a garage.

very nice, Castrol should be fine, the zinc additive will keep you in the clear. I have always had pretty good luck finding the VR1 at most of the local parts houses.

 

[ColoDisco]

I found VR1 just not in a 10w.

Back at it today.
Installed the intake.

Got on a roll, installed rocker covers, upper intake, hoses (vacuum, fuel, evap and coolant), cap and wires.

Installed serp tensioner and belt.

To finish up this afternoon, I am installing the radiator, shroud and waiting on the fan for access to the crank bolt, plan in feeding oil into the radiator access to the oil pump and cranking manually to build up the prime.

 

[ColoDisco]

Really close. Doing the cam break in tomorrow morning.

Finalizing:
MAF and upper air box installed.

Radiator installed

Air lifted the cooling system

Hey colo how does that 'air lifting' system work? Does one need that to apparatus just to flush the coolant and get all the air out of the system? I know I need to change the coolant on mine, but don't know how simple of a job it actually will be without something like that.
