In the interest of future users and as suggested earlier and speaking to 82911 on my bearing clearances and how my builder has shimmed the pump to the engine, we have decided to run the H/V for now and see where this all ends up. If it still pumps up I can then change to my new std pump.
I will keep all interested parties informed....and Yes...that is a roll pin and his mod works a treat...gotta love aussie ingenuity!!.

I would be more comfortable with the idea of using a roll pin than using pipe cleaners.

Brands and pictures please.
I was always worried that a roll pin may gouge into something if the pushrod end was not smooth as.

sorry rory,i have lead u astray.the roll pins didnt come in the box with the pushrods.my engine builder bought them home from his work.he was going to use them,but changed his mind.it looked to me like they came together.when i first saw the pushrods,he had the roll pins in his hand,with the pushrods.
anyways it seems like its the way to go.as far as my engine builder is concerned,its ok to use roll pins in pushrods
im watching this closely because ill have to do something to.on the dyno i blew the elbows out of the standard vn covers.but there was absolutly no trace of oil coming out,at the moment

Sorry to bring back up an old thread, but what was the conclusion on this matter?
Did the .050 hole in the push rods restrict the oil flow to the rockers? have you stuck with the high volume oil pump or did you go down to a standard one?
Im going to ring the guy doing my heads and get him to drill the drain holes on my VN heads to 10mm.

Another oil question for you rory.
Has anything been done in your engine mods to address lack of oil on the cam.
Seem to remember this being an issue in the 80s.

i just rang the bloke that is doing my heads and he measured the drain holes to be 11mm Measured a few others that were 11mm too.
Hmmm. Whats the go with that ?

Hey guys,
Just thought i would search for the "answer" with oil up top and catch can setups has anyone else got some photos of their catch can setups?
I definately have an issue with oil/blowbye/breathing/ at high RPM and am keen to set up a catch can after looking on evilbay height seems that it may be a problem with most catchcan setups offered . I have my radiator overflow "catchcan" mounted on passenger side front of head at present .
There seems to be plenty of room behind drivers side headlight for a can but height is a little restricted anyone want to share their setups ?

G'day,
Just wanting to get some thoughts on oil catch can issues for my LC. Firstly I am useless mechanically, and so have anything done on the car by my Dad's mechanic. I purchased the car almost as is, but recently have added an ASR race sump, and the mechanic then added this new "shiny"
catch can and fitting etc which on Sunday just gone, spewed all over the place. (really could not give a shit about shiny..just want it to work)
Previously the car had an upturned 4 litre oil bottle with some clear plastic tubing, and all was fine!
So after some advice and help from friendly racers, I blocked the lower line that connects back to the front of the block. They said that as Sandown was mainly all left hand turns, all the oil will simply run straight up the line and into the can....which is very small.
Does anyone have any suggestions to a decent race setup? My thoughts are simply to get a large catch can from somewhere (like what I had but "shiny"), and then remove the lower line back into the block to stop the oil from rushing up on left hand turns.

I wouldn't have it returning to the sump at all.
Rather a tap to drain it after a days racing.

Right ok. I have seen cars with or without this return to the sump. Seems strange that there would be such varying views on this return.
Yeah, sorry I forgot to mention at the bottom of the can, there is another screw cap to drain the unit.
Which leads me to another question, on Sunday while draining this, I noticed that there seemed to be maybe 1/3 of a teaspoon of grit/sludgy substance which I thought was quite perculiar. Any thoughts on what this would be?
Thanks for you thoughts.

Hey Westie
Probably remnants from the fabrication of "shiny" can inside of it prior to you useing it.
Good to know but,when i do actually get a "shiny" can i will give it a good flush before useing it.
It also interests me the different views on re-useing the oil in the catchcan. I can't see a problem in reuseing it if you drain oil into a suitable container and refill engine straight away after you have been out in the car?
Thanks for your photos mate ,surely there are some more setups out there.

The breather line looks a little on the small side, how does it compare with the system you replaced?
I would consider drilling out the breather location on the rocker cover just behind the filler cap and running a second breather line to the catch can. If you do drill out the second breather then make sure you fit a baffle inside the rocker cover.
