Lifter failure cylinder 1

Post by nmargrave » Mon May 11, 2020 3:10 am

Had lifter failure on cylinder 1. Damn..... Drove it for about a mile and parked it. This happened months ago and I am just getting around to posting about it. Because I only drove it about a mile, it did not chew up the cam too bad. Had multiple bent push rods too. Damn. It was a big job as I am a weekend warrior when it come to working on stuff. The plastic lifter tray failed and the lifter was able to spin aswell.... glad I parked it or it might have turned into a full DOD delete. Car has 9000 idle miles, I wonder if that had something to do with it?

This guy seems very knowledgeable and really help me out fixing the car. Seems like he does a lot of DOD repairs and knows his stuff. Bought his tool and plug tried it.... Tool did not work, but used the plug.

I've seen his videos and he does have good ideas that seem to work for getting the lifter unstuck. However, I'm not too fussy about his modification to the VLOM except the plug. The plug alone would be enough IMHO or it should be replaced by the non-DOD valley cover to do it right.

BTW, just so you know, 9000 idle hours is equivalent to 900,000 KM (560,000 miles) as the calculation used is 100km/idle hour. It's common for these engines to wipe out the cam with a failed lifter tray with high idle hours.

I was definitely lucky that I parked it when I did. I will get a picture of the lifter on her when I can. Put about 2000 miles on it since, the ole girl is running strong.
