Thanks a lot for input. Chain wore right through the cover spilling coolant into my engine oil. Thankfully i have a spare 22r in the toolshed. Annoying thing is that the timing chain and guides were new, only the "quality" plastic guide broke and thus my problem.
The cover from my 83 22r is different from my april 84 22r, also i tried to put a new dual row chain in from 83 and it would not fit( too big ). When you put your dual row chain in, did it seem a bit too sloppy to you? mine would actually skip when i turned over the crankshaft.
