606 lifter question
 

1999 E300D. Long story short. Bought car with broken GP. Tore it down and put it back together over the course of around 7 months the way time goes. When I got it back together the engine was very loud much louder than normal. I checked everything. Eliminated the injectors, timed IP, made sure cams were in time. Now I have it down to the lifters and I can't push the lifters in using my hand. Is there a chance they could have became stuck being out of the car for so long and not working right now? The noise seemed like it was coming from the whole engine and I was kinda suspecting lifters but have read were they aren't a problem area on this particular car. But also most of them aren't sitting on the shelf for 7 months. Please let me know if I should be able to push the lifter in and out. All of mine seem stuck.

It's common for the lifters to stick. I have squished them with Channel-Locks or a vice to get them limbered up again.

Just put a rag around them so they don't get scuffed or squirt oil everywhere.

It was indeed my lifters, all 24 of them had stuck. I gave them an oil bath and worked them in a vise and a couple hours later they were all functioning. Car is back together and sounds GREAT......

Cool, good to hear it!
