Compression issue? Parts and guide to fix

Alright today is the big day when the project starts. Lots of photos to follow and even more questions to be asked.

 

Just found this video, made it look very easy

 

Having done this a lot...

Remove the entire exhaust system first, it's very heavy and you won't be able to get it off later.

By FAR the easiest way is to disconnect everything and pivot engine and box down on front GB mount. Then separate engine from box. This way all you need to remove is the plastic part of the oil filler.

If you try it with GB firmly in place, you'll need to remove a stack of parts at the rear in order to pull it back far enough to get it free of the gearbox and it will be very tight. EG cannot be done on mine at all as my 74 is just 10mm more cramped than later models.

 

Amazing advice currently struggling to get my hands on a trolly jack at the currently moment,

 

Jack needs to be big. Not a little thing you can pick up with 1 hand

 

I’m very confused here, there still not definitive problem but you’re going to take the engine out? , have you set the valves ? Have you checked the cam followers, cam lift ? , you can do all this in an hour with the engine in place and run it to see if it’s fixed, valves not properly opening can cause high and low compression issues, this could be a simple hours worth of work fix.

 

Correct

 

Amazing I will do this all now know harm in trying plus with out a trolly jack I cant do it any way

 

Read page 6 ,the How to do it is on there

 

Check the pushrods are all sitting in their happy places as well while you've got the rocker covers off...and double check they are the right ones for whatever engine you've got.
Iirc and @zedders or @davidoft will confirm, pushrods for hydro engines are shorted than non hydro. Therefore if solid lifters have been fitted with hydro pushrods, you'll never get it set right.
Like David says, easy to do firstwithout pulling everything out. Sorry if this has been suggested before..it's a long thread haha

 

Non hydro are fat aluminium, hydro are thin (steel I think). He's already had the lifters swapped and been shown one of the old hydro lifters.

I would be fishing out the lifters and looking down t'holes though.

 

Cover off
Van on ramps

Lot of oil inside of the cover?

 

There is supposed to be oil in there so that's good.
If you are on a cambered road, the down hill side of the engine won't drain back to the sump as completely as the up hill side. I usually just jack up the side I'm taking the cover off then have a cuppa before removing it. Keeps the drips off the HX.

 

Start with the number 4 , as that's the lowest reading.

 

Yup, good shout. Can check both lifters and rods are compatible at the same time

 

Getting there finger in hole feels fine

 

Put those rods in a box. Grit and dirt will ruin it. CLEAN,CLEAN CLEAN.

 

Or at least put the bits in the valve cover you just removed for now. Then something with a lid because sods law a gust of wind will contaminate the lot with dust and grit.

 

Finger in hole feels fine. **smirk**
This is TLB, mind how you phrase things.

What hole?

Pull the tubes out through the head, start with the ones that weren't moving far. Then fish out the followers, inspect and look down THAT hole at the cam lobe.
