Before things go sideways, is the 318 engine one of the ones that the flywheel can get out of sink with the marks? Or is it late enough that the flywheel only goes on the one way. With all the late model updates this could well be a machine that has had a lot of work done to it over time. This increases the chance of the flywheel having been off.

You don't say which 3 are not firing. But by chance is it the front 3? That would indicate linkage trouble with the compression release mechanism. Because the valve cover is 2 pieces and I don't remember how it all connects together. But if the valves are held open that would explain your problem. Just a random thought that would be easy to check. But I fear with the poorer quality of "new" diesel fuel, fuel problems will become more

Its 3, 4 & 5 that arnt firing.

That means my idea is out.

On the subject of flywheel to crankshaft chisel marks.
The marks seem to be done at random during assembly . Therefore the marks may only be true if using original matching crank and flywheel.
This can also be the case with timing marks on cam gears and other engine components .
When assembling an engine all timing marks should be checked to correct position of relevant parts.

It totally failed a balance / leak down test today. So back to the original post lol wheres a good place to get engine rebuild parts ?

Well we pulled it apart today and found two sets of broken rings, probably from ether is my guess, and some crazy wear on the liners, way past just catching a fingernail with. The odd thing (at least in my opinion) is that someone has been into this motor not all that long ago, the head gasket is brand new, nothing at all was seized, every single thing came apart easy and it looks to me like it has a new or reconditioned head, it is also very clean in there, no buildup at all. What makes me shake my head is to go in that far, theres no way that you wouldnt see the amount of wear in those liners, why not finish the job properly.... The head probably cost as much as the liner and piston kits.

So advice on part sourcing ?

Could have broke the rings when "bleeding" the fuel system after the head job. There are lots of parts out there for the 318.

Regal has a good reputation for parts

How does one break rings when bleeding the fuel system ? Neither my dad or I have ever heard of that and he has been a heavy duty mechanic for a long time...

Bleeder in a can ( ether ) used in large amounts will do it. I have seen many lazy people use the can rather than a wrench.

ah okay ill agree with that for sure, there are way to many people out there that dont know how to use starting fluid. this one has had direct start put on it which in my opinion increases the chances of ppl dumping a can of ether in it.
