Twincam - Cam Cover

Hello all
Attempting to reply to contributors, however, my reply appears not to want to post, not sure why, will try again tomorrow.

Thank you

First off best of luck with your health. We are all getting older so good health is not a given anymore. As a person who did a lot of machining in the distant past I would recommend filing some sort of reference flat on it probably on the front or rear edge. Set it up vertical on a table and make sure the sides are perpendicular to the filed area. Use a carpenter square maybe. Measure on the head the distance from the front edge to the center of one of the long studs retaining the cover. Precision is key. Make a second measurement to the back row of studs. This will give you the front to back dimension.then measure the distance left to right of the sets of four studs. Establish a center line for the cover by measuring betweenthe gap between the two sides find the center of that and you should have the pattern.it would be easy to dial alk this stuff on a bridgeport but probably doable with a nice ruler and scale

Good morning,
Thanks to all for the valuable input into my amateur engineering exercise. Given the amount of information received I should surely be able to work this through, hopefully in the near future.

If I had an engineer sitting here in my conservatory it would likely be done in quick sticks however it may take me a little longer.

Thank you again

Hello Mark
Thank you for your good wishes and positive encouragement, I do appreciate it. I think you are correct when you say that some contributors on this forum just play the game however, we will surely lose no sleep over that.

A reply to the observations that I have not posted feedback and updates on my success or failure of my previous two small projects, this would of course be due to the lack of any progress whatsoever, for reasons already noted.

Best wishes to you in the Wirral

As a suggestion try the following,
1. Check vertical straightness of cam cover studs and check, from centre to centre of studs from front to back,
and side to side, to ensure none are warped and prevent cover going on square.
2. Set a straight edge up the front of the timing chest projecting above the height of the cam cover studs, or get
someone to hold the straight edge
3. Measure from here to the centre of each stud
4. Similarly set up a straight edge from either side of the head
5. Measure from here across the studs
6. Set up the cam cover with a square block of timber to first the front edge and then the side edge you took
measurements from
7. Mark position of studs as you go
8. Centre punch holes and drill with necessary clearance
9. Lightly deburr around holes and trial fit cover
10. Should any adjustments be necessary, which should be very marginal if measurements are correct, then
increase drilled holes slightly to give a little wiggle room

Job should work out fine, but it may also be worth checking flatness of cam cover, if as it sounds it may not have been fully completed originally.

But let us know how you get on and what method you finally chose.

JJ Dikke. Are you the same JJ Dikke who is posting on the "Old Skool Ford" website? The one who would appear to have a rather nice Mk1 Escort (amongst other cars and parts) and who was posting on that website until quite recently with seemingly no signs of ill health.

If I have made a correct assumption then please kindly remove yourself from this forum website. If you aren't and I've made an incorrect assumption I do apologize.

A lot of your posts are quite unusual and whilst I do appreciate a bit of humor now and then this has gone on for long enough.

I'll let others Google your "JJ Dikke" name and find out for themselves what comes up.

Good morning all,
Firstly, thank you to those who have wished me well in respect of ill health. I am advised by my hospital Consultants to maintain a positive attitude, take one day at a time and try to retain my sense of humour, prostate cancer is not good, another MRI scan soon.

Now this is exciting, I am currently sitting at my kitchen table with the following items, 2 cam covers, 1 drilled 1 un drilled, 2 steel rulers, 1 steel straight edge, various marker pens and my cardboard template.

Following the various directions I have been helpfully given I have decided to try the different methods suggested prior to a pilot drill hole through the cam cover. If I then remove the drilled cam cover I should be able to see how the marks line up on the 8 flats of the un drilled cover. This should tell me if they are central.

I suppose my best bet would be to purchase an additional cylinder head which may assist as a test bed. As one contributor said, measure twice, drill once.

No progress to report on my aluminium sump and my cam cover with overly large drilled holes as these simple but enjoyable projects have had to take a back seat for a while.

Thank you all once again.

Don't forget that if the holes end up slightly off you can gently knock the studs at the top (use a soft mallet and put a nut on the thread to avoid damage) to adjust them so they pass through the cover. You find that this is the case a lot of times when fitting a different cam cover to a head as the drillings are never that accurate across heads and cam covers.
