Shovel is smoking from oilcan and oilfilter? Why
 
I have just bought an 66 flh with a 1200 shovelhead, it was bought with a issue - it runs perfect but it smoke grey/white from oil tank and oilfilter and when i drive a very short distance it seems to press oil out of the 4 bolts on the heads?

My oil pressure is fine - is it compression thats running in the crankhouse?
I have checked the bleed valve in the oil pump not sure if its closed or it opens

That is the most likely cause...your rings are worn and causing "blowby".
You need to do a compression test to confirm it.

2 years ago mine was building pressure in the oil tank and smoking from the pipes.
Ringes were worn and my breather gear was worn.
Replaced that and got new rings, problem solved

I bought the bike yesterday, with the issue the owner told me all problems had come after it had been set away for winter no problems last summer, and compression (driving) and starting is perfect, starts evey first time.

I was thinking i will remove the oilpump and check it, then i also will do compress test/leak, it seems wierd that it have got new oil and filter and the oil in the oilpump on one site is totally clear and in the other its black , like its not circulate.

Sorry for bad english writing

What kind of oil filter? If you put a filter on it that has an "anti-drain-back" valve and the hoses are not hooked up correctly...no oil will flow though the filter...don't pull the oil pump just yet.

that pump is a very old aftermarket unit - the oil return line is plugged into the oil pressure switch location on any other pump - i also believe you have a ring and or piston scuffing issue -

as for the rocker box screw end cap leaks - they have O rings and with the heat get brittle and hard and cant seal any longer -- Today we use the white nylon quad cut seals instead they work very well - i would take the top end off the cam cover off and have a good look around - if you drive it all summer you could hurt it even more sucks but you did buy a bike with an issue

Not meaning to jack the thread but can you tell me where you get these and maybe a part number?

To the OP...welcome to the Shovel world. If ya get a chance, how a bout a few pics of your new ride?

It appears to me that you have another issue. If you bought a 66, the motor appears to be a 70 or later. A 66 would have a flat gear cover and an upright circuit breaker. A 70 or later has a cone shaped gear cover and the circuit breaker is at the end of the cam shaft.

And...The VIN should be on the Case on a '66. Certainly Not True on a Cone Motor....Post '70's have the VIN# on the Frame....

what a great spot - missed that as the pump did me in i had not seen one in 20 years - he might not get what you are getting at - you have a picture of the bikes first 2 numbers and the first 2 or 3 letters - the rest of the numbers of how many was built you can cover it up its not important
