- The bottom end is done, so we move on to the cylinder head.
It all gets disassembled and hot tanked to get the gunk out. The intake valves looked good, but the exhausts needed a lot of work, so I gave those a good lapping. This is a budget build, so a full valve job is not really an option.
It also gets new valve stem seals, which may have been a contributor to this engine's oil consumption.
I just binge watch all the m54 videos. Motivated to rebuild mine. Awesome and detailed.
I’m rebuilding my M54 right now and I’m not going as into depth as you are, but it’s insane how much there is to know about these engines and how people like you know it so well
The "e" on the intake tray and the "a" on exhaust side are actually German markings and stand for "Einlass" (intake) and "Auslass" (outlet). Greetings from Germany
For the retainers on the valves while you Compress the spring I was taught to use silicone grease to make both of them hold while you release the spring
makes the job that much easier without them falling all the time 😂
Cool I'll be sure to use that next time! The oil seems to work well, but even assembly lube would have been a better choice.
I normally use magnetic spark plug socket and hammer to remove the retainer, put the socket over the spring and tap it with a hammer done ....
A small flat head screw driver and bearing grease to reinstall the retainer , it will just stick on the grease , and release the spring compressor, way more safer than using engine oil to stick the retainer on to the valve
Do the valve job before assemble the valves, those grinding compound splash when u lapping it , clean the whole head thoroughly and perform leak down test , and don't be lazy
I've rebuild tons of engine and screwed up sometimes as well, thinking of shortcuts and being lazy
Luckily this is just a cheap hobby build
In a future video can you give us a rundown on the parts you bought, cost and labor time it took you to refurbish the engine? Thanks
Yeah I'll try and do that. Spoiler it's about $800 and probably 20-30 hours of work, most of which is cleaning parts.
What kit did you use, can you give a full parts list?
What are you using for washing parts?
Big tub of hot water and simple green. And a lot of time.
hi there. i saw u had a -40 Celcius on panel on some other video. what is the problem? i need that fixed. ^.^ is that MAF?
No it's ambient air temp. It sure is cold in the garage. Just kidding, the sensor wasn't plugged in.
Acid use for cleaning 🧐?
Just some lacquer thinner
What happened to the 330 track car?
Still have it and still working on it, haven't gotten around to making more videos yet. The rollcage is taking quite some time.
