These will put the proper amount of oil pressure for the 4-134 motor and have a high pressure relief valve as well. Sounds like it may not have been primed prior to install.

It should slide down. Keep in mind the notch on the end of the oil pump goes into the tooth on the end of the distributor too. This can cause it to stick as well as the gear to gear contact on the camshaft.

I wouldnt think so, it really will just give poor oil pressure. But if you have chipped/broken teeth on it then it could be doing serious damaged to your camshaft and cause vibration or worse.

It shouldnt ever go over 40, the relief valve opens at 40. At idle minimum safe pressure is 6 psi at idle. At 2000 rpm (35 mph) it should be at least 20. So it sounds like you are ok.
