Hi all,
Photos below show what I made up. Just a very simple bit of 50x25x2.5mm RHS rectangular with an eye bolt in the middle and two bolts at spacings that match the distance between spark plugs 1 and 4.
No need to get too fancy with drilling out the holes for the bolts, a little bit of clearance makes it no real difference as we are not trying to lift up the Queen Mary. The steel was scrap so the most expensive part was the bolts, they are grade 8 M18 and I think they cost around AUD$5 each.
The tape on the tread was an indicator to ensure that I got the bolt all the way in to the head but no more (no point in driving it in to the top of the piston).
What I like about this design is that firstly it gives you something to pull on to remove a head and if it's really tight then just attach it to a block and tackle and slowly apply some force with maybe some gentle tapping with a soft hammer to encourage things along. If you lift the car off the ground then either;
a) you’ve forgotten to take a nut off one of the studs; or;
b) you have some serious issues and it’s time to walk away and have a cup of tea and a lay down.
The second reason I like this design is that if you attach it with the head nuts in place it’s an excellent tool to lift the entire engine and gearbox out of the car. The eye bolt connection allows you to rotate the engine around the east/west axis and with my deep sump that’s a big plus.
