its called crosshatch, its purpose is to retain oil on the cylinder wall.

Using paint thinner to check for leaking valves works well. It's thinner than water.

The work for the cylinders your looking for is not glazing it's called cross hatching. Glazing is bad it's what happens to a worn cylinder with lots of use.

Glazing can happen on diesel engine very easily , if the engine is not working hard then the cylinder will glaze . Usually a couple days of 80% load will cure it

just got a yanmar L100AE because these things are fun. got it started but it was stuck in full throttle! the clowns installed the injector pump wrong. the pump throttle was not mated with governor fork! it was a simple fix 😆

Just bought 3 of these, & they all have the same issue. Got one to barely run, but life you said the carbon is probably keeping them from sealing up completely.

Hello. Nice videos you post. I have a Yanmar L100AE in a Mase generator. Valve and valve seats are ground, but it will not start without starting gas. Does not need much starting gas to start. The cause of the problem is salt water that came in via the diesel tank. Could it be the piston springs that are broken? Or a lot of rust on it? The cylinder walls are fine. No scratches or worn cylinder walls. There is a new nozzle on it, and I have checked the diesel pump, and it works ok. Unfortunately I do not have a compression meter for it, so I have not been able to check the comprresion. Going on holiday, so all tips are most welcome. Thanks in advance from Norway.

try pouring acetone, and automatic transmission fluid into the cylinder and see if it only leaks through the rings into the crank

Big question, 3TN66 JD332, low comp so removed the head and changed HG, new valve seals, lapped valves and cleaned it up. Put back together and no compression at all. I can turn by hand. I set the valve clearance and when apart the cyl bore looked perfect. It has about 2k hours.

I have a yanmar ydg5500e and it started blowing oil from the governor linkage seal. Is it safe to assume there's excess pressure in the crankcase or would I be fine just replacing the oil seal? If the problem continues, is most likely the rings?
@michaelbenoit248
3 жыл бұрын
It’s probably the rings. There shouldn’t be that much pressure in the crankcase. If you take the oil cap off, & see a pulsing then your rings are shot.

The original scoring on the liners is called the hone marks. Glazing is what happens to the liners when hot combustion gases blow past the now poorly sealing piston rings and creates a glaze on the cylinder bore & increased oil consumption.

Hey dude, we bought an excavator with a single cylinder diesel engine. The oil was too low and didn't have a cutout switch connected. Now we can't get compression. Any ideas? I'm guessing piston rings or valves, but Idk what kind of damage low oil might have done to it. The bastard only has 9 hours.
@zippyzappyz

William Manche check the valves first!! These engines are super tolerant just like an old 7.3 and cummins engine is. Also check other simple things like the engine head torque etc. can also take the injector out and pour a mix of acetone and marvel mystery oil to see if it’s just a seized piston ring or two! After all that, if there is still no compression, then a rebuild is most likely needed
