I know it sounds a bit extreme but my engine builder recommended that the spark plugs are removed when the oil is changed! As it would have no compression it would not stress the big end bearings.

I have done quite a few oil changes on my scoobies in the past but never taken the plugs out - just filled the new filter and removed the crank position sensor while I turn it over to get the pressure up.

What's thought on this?

Any advice would be appreciated.

I disconnect the crank sensor, but that's it. Have heard of removing the sparks before though.

Why not warm the new oil up also?
Cant be to careful!

As long as the filter is PROPERLY topped up before being screwed on, you shouldnt have to do any of the above.

Good thinking.

This ^^^^

Never had any issues with oil changes doing this...takes an age to fill it though.

Thats it. It does take more than youd expect and a fair bit of swirling to get the oil round into all the cavity in the filter.

Im running a syvecs too which is set to crank a few times to check sensors before it fires.

Probably worth me saying this is just my 2p! I dont expect any stick for it or blame if someone follows suit and trys to make out theyve dropped a bigun as a result.

Fill the filter then disconnect crank sensor, turn over till I get pressure on the guage, re connect then job done
