@@FriendlyMBTech All Thanks To You Sir ... Am Keep Smiling When I Watching Your Video's Because Am Sure That Am Learning Something New Every Time ...,,,, respect
Good morning my friend. Finally I've watched all your videos and now can watch every week. This job is very complicated for me so I will know what I'm paying for if I have to. And I saw the spark plugs from inside. Now I can imagine how it works. Thanks. Keep going!!!
Hey FNT. As usual your videos are very helpful. I’m sure I need to do a similar thing to my 560SL. I noticed you didn’t clean your valves with a wire brush wheel. I’m guessing that may scratch the valves? I’ve seen other Chevy videos and they used a drill with a wire brush to clean the carbon. Just checking so I clean things up the right way and not damage something.
Yeah I didn't want to go hog wild with a wire wheel like that. I just wanted them to seal properly to the valve seat and the stem seal. Other than that the carbon is just aesthetic. It won't cause any change in how it runs unless it starts affecting the seat surface or the stem seal. In this video I did experiment with various "valve cleaning" products. Even soaking them completely submerged over night didn't do anything to that carbon.
Hello Mr. FNT - Curious as to why you didn't just send the heads out to a machine shop and have them dunked (cleaned), and measured for straightness. They would have come back to you nice and shiny and factory fresh looking, and probably would only cost $100 or less if you disassembled everything. This is what I did on my M117 and M104 rebuilds.
The machine shop we use is about $250 - 500 per head and is a couple hours away. I'd trust that place over a closer shop I've never worked with. Also, I can't make a video on a machine shop doing the work for me. I have a straight edge, I can measure for straightness and the heads don't have a lot of carbon build up. The turn around on sending the heads out would be weeks and I didn't want to add that much time sitting around waiting for them to get back. The most important reason is that I am having fun doing everything myself.
@@FriendlyMBTech Dang, yeah that is expensive! When I lived in Houston we had a very reputable machine shop (all the Houston Benz dealers sent their heads there) that would do both heads for $300 or so. And my M104 head was like $250 out the door. In both cases they skimmed off a very slight amount even though neither engine's heads were warped. Love clean heads. That's a super long turnaround time. In Houston my turnaround was 1-2 weeks. I am glad to see that your engine is an early one that has the metal cam oiler tubes. In the late 1992 time frame, they started installing the plastic cam oiler tubes as a cost-saving measure. Whenever I find an early M119 at the wrecking yard, I get the tubes from the heads and sell them to folks on my forum. They go for $150-200 a set, with new o-rings. The plastic tubes are junk. Another hot M119 mod that some of my members have done is to retrofit the late style belt tensioner, which is MUCH nicer to work with than the fiddly early one. It takes a bunch of stuff to fit it (not just the tensioner itself, but the plate it fits to) but it is a nice mod for a long-term owner.
@@FriendlyMBTech thank you so much for replying sir! Now I reclaimed lots of motivation! Gonna buy some of that paste tomorrow! M119 is my fav engine & it's the first time I disassemble a motor AND PUT IT BACK TOGETHER hahah... I got some experienced friends to ask about stuff sometimes, but don't wanna nag on them. Besides. I feel like you:re the M119 guru hahah
