Any Mechanics here?

I want to do two jobs to the head of my blue 202.
1. replace the hydraulic lifters = Can i do this without removing dizzy & side plate. Are they removable under the tappet cover & rocker gear?

2. I also want to replace the Valve stem seals, can this be done without removing the head. I realise you need the head off to compress the springs but was wondering if anyone new an easier option.

Oh p.s Ive been quoted $105 for a 3 speed transmission service in vic. Sound about right?
Cheers

To repace the lifters you will need to remove the rocker cover and rockers, pull out the push rods ( keep all parts in order(1 - 12)). You will need to remove the side plates - as the lifters are behind these. I would pull out the dizzy too, you'll have heaps more room. I've never tried to do the lifters with the dizzy still in place.
You can now pull out the lifters (I use a small screw driver) being carefull not to damage their bores.
They will probbably be gummed up a fair bit so work them up and down a few times ( spray on some CRC round them. this may help soften up the crap that stickes to the lifters.
when they are all out clean the bores, push rods & rockers thouroughly , paying exta attention to the insides of the pushrods as thats where the oil flows through upto the rocker gear.
Be sure to lubricate everything when you re assemble and prime the new lifters.
Some manufacturers say "no priming required" but at first start up you want oil pressure as soon as possible so it pays to prime. It will greatly increase their life.
Last, don't skimp out, put in new oil and a filter. Why put dirty oil in your new lifters?
good luck!

Please use, Holdenpaedia will get the first box on the left side. Post any suggestions.

The valve stem seals can be replaced with head on. I've done it.
The way I did it is to take out all your spark plugs.
Remove rocker cover and rockers.
The next part will sound weird but it works.
Turn the crank till No.1 piston is all the way down.
Find small rope (nylon 6mm. works well) and feed it in spark plug hole no.1 till the cylinder is full. leave some hanging out.
Next, turn the crank by hand. This will force the rope up against the valve heads.
Get some flat bar 20mm x 4mm long enough to go over each cylinder's rocker posts. drill 2 holes a bit bigger than the posts.
Fit this bar over the two posts and put a nut on each - just enough so the post protrudes.
You can now use a ring spanner under this bar and over the valve spring retaining cups.
Compress the spring and remove the collets.
remove the spring(s) and remove the seal.
Check the top of the valve stem for burring.
dress carefully only the edge with a fine oil stone before fitting a new seal.
Put it all back together and move to the next valve.

It does work and will save time and money. head removal requires new gaskets (head, manifold, thermostat etc.)

Regarding the auto service $105 is ok if they do a good job.

Good luck!
