It's usually in the periods of 'hanging around' I like to think I'm at my most dangerous to the budget, as the original plans change in the early phase or at least the larger items are sourced, my attention starts to turn to all manner of smaller items and it is normally here where the budget slips on such odds and ends like pipework or even screws.
One source of amusement for me to play with has been the clean up and finish on the RB26 covers. As posted previously the front pulley cover needs to be modified for the Variable Valve Timing which sticks out the front of the RB25 engine.
I also wanted to go with a classic feel for the engine itself and being of advancing years I recall from my youth that anything 'cool' would feature a red top engine. Just say no to flip paint, to manga girls in states of undress and Japanese flags. Oddly enough you would think it easy to get a rough finish crackle powder coat although there are not a lot of places who actually do it. Eventually I found Maldon Shot Blasting who do a lot of restoration work on classic cars. It's pretty important to remember that not all powder coaters are equal at this point, what works for your garden furniture does not always hold true for your pride and joy. Otherwise this is known as 'getting what you pay for' (crap is crap).
Anyway onto the main course..
I started out with some respectable second hand covers that had already been well painted in a flip HKS type purple. As you can see from the photo the front cover was then modified to take care of the VVT bulge and the ghastly RB26 was sanded away.

No more rattle cans giving an uneven or inconsistent finish.
Available from stock. In Ferrari Red or Black.
Maldon Shot Blasting & Powder Coating Ltd. now offers a new Crinkle powder coating system for a variety of cam covers and engine parts in Black or Ferrari Red. This new system has been approved by three local car restoration companies, JD Classics, Fox Hoyle Racing & Jennings Engineering.
Our work is carried out to a very high standard; for instance cam covers are chemically stripped (no acids are used) then washed and ultra cleaned in our phosphate plant, threads and inner chambers are then masked off.
Some clients require us to mill off raised areas of the work such as logo’s and ribbed parts for a better effect. This can be done in two ways, either by a simple D.A fine sanding of by milling. Milling leaves a far superior surface, however this will add further costs to the work as a local engineering company carries out this work on our behalf.

If you are interested in this new powder coating finish, we would be happy to run a small sample, using parts supplied by the client. Sample swatches can be supplied on request.

Fitting the AN10 bungs. These are supplied slightly oversize for a tight press fitting. However you don't have to worry about hiring a giant press to fit them! I used some copper slip for lubrication on the shaft and inner diameter.
Pushing the fitting in by hand so that it lined up correctly I then covered it with a cloth and gave it a couple of good taps with a weighted non rebounding plastic hammer.

The main centre cover bolts are M5 x 25 Cap heads. Although there are two at the end significantly smaller.
Here are some gratuitous shots of the finished item so far.
