hi peeps. gonna be changing my lifters and stem seals tommorrow. what i'm wondering is as never done this before, do you simply put a socket on the crank pulley to turn the engine to tdc or is there an other way. just thought i'd check even at the risk of sounding daft.

 

yes, thats fine - take the plugs out and it's much easier to turn.

Don't bother changing the lifters if your not changing the cam....

 

how come?

 

because they will be noisey again after around 100miles. New lifters need new cam The cam will cut the new ones to bits in no time.

 

new cam it is then.

 

Waste of money otherwise mate.

 

You can also put the car in say 5th gear and gently nudge it forward to get it to TDC, it can be tedious using a spanner on the crank pulley

And as Rick has already said, CVH cams and lifters need to be done in pairs, i learnt the hard way however

 

size 19 on the crank bolt - rather tedious

what i have done to make life easier to remove valve springs as follows:
get a big open ended spanner(20 mm plus)
lay this on the valve spring retainer with the other end of the spanner towards the cam laying on the rocker stud
with the rocker removed , mark the spanner where it touches under the spanner
drill an appropriate hole through the spanner
attach your new "tool" with a rocker stud bolt and compress the spring - sorted!
you now have a spring compression tool
a modified plug with an air compressor attached will keep the valves up , alternatively , use some nylon rope , feed into the chamber , rotate the piston up

 

AFPMSL!!!! What a classic.

Rather than waste a perfectly good spanner, buy a proper valve spring compressor.....

That makes the job alot easier and they cost next-to-no money.

The references to TDC are made simply to avoid dropping a valve into the cylinder. I always wind mine over on the cam pulley bolt. To be honest, the old seals may be loose and the valve will slide down, but once the new seals are on, the chances are they will hold the valves OK. The valve may slide down only as far as the ridges anyway.

Here's another tip for you too.....

Get some kitchen roll and lay it around the inside of the head to cover the oilways, because if you drop a collet down there it's sump off time!! Just take care not to trap any of the paper under the stem seal or spring and make sure you get it ALL out.

 

Fairplay to him though if he didn't know about the tool

 

u should see the size of my tool

 

cheers guys. must admit it seems a shame to destroy a spanner when you can get the proper tool for the job. thanks again for the tips guys

 

I heard you are a tool, not you've got one
