I have a 89 TPI and it has started blowing a serious amount of oil out where ever it can..... It has blown the oil cap off once and the dipstick multiple times....naturally I assumed too much crankcase pressure so I replaced PCV valve (which was clogged) but it didn't help and it still blowing oil through dipstick tube....... Any ideas would be GREATLY appreciated thanks

Have you checked the PCV valve to make sure it's working? Even though it may be new, it can still fail. Also, there's a baffle inside the valve cover. If it's plugged/pugging, the crankcase pressure will increase.

Check your cyl. compression. Could be bad rings.

if the pcv is operating, then its blow by thats getting bad, and prolly time to go "30"over
