Another 914-6 GT Tribute Project Options

[Tom1394racing]

I installed the chain tensioners today and rechecked the cam timing. I am using the late 930 (non-pressure fed) tensioners with the later wide bushed idler arms. I am also using the tensioner guards as extra protection.

I use zip ties (rather than the Porsche special tool) to hold the tensioners after compressing them in my bench vice so they can be installed. The zip ties are then cut and removed allowing the tensioner to expand.

As expected, the cam timing remained unchanged.

Looks great

Thanks Ben

I am sure I will be getting in touch with you for guidance on the oil line system I bough from you for this project.

I spent the past couple of days finishing up the long block.

I did the piston-to-valve clearance check by screwing in the intake and exhaust valve rocker adjusters on cylinders 1 and 4 by 1.5 mm and 2.0 mm respectively and then rotating the engine through several revolutions to check for interference. No interference between the pistons and valves means that there is at least 1.5 mm intake valve clearance and 2.0 mm exhaust valve clearance.

After assuring adequate piston-to-valve clearance I installed the JB Racing billet twin plug distributor and set the top rotor to the Z1 mark on the distributor while the engine was at TDC of the compression stroke for cylinder #1.

After this, I installed the remaining rockers, adjusted the valve clearance and installed the valve covers.

I then decided to recheck the engine oil cooler for leaks. I planned to use a 911 cooler that was modified for the 914-6 configuration with a welded in elbow. I had checked it with the Stromski pressure tester before sending out for the -6 modification and did not see any leaks. However, upon rechecking it, I got plenty of air bubbles. So now I need to find a replacement 914-6 style cooler.

Wow! That long block looks great. Sorry to hear about the oil cooler leak but so glad you re-checked it before installation only to have to remove it after you fired her up. (IMG:style_emoticons/default/beerchug.gif)

Just got back from a nice long vacation and found the new cooler had arrived. In an abundance of caution, I repeated the leak check and as expected, no bubbles.

I installed the new cooler but it has a standard M30 fitting. So now I need an M30 X A N12 adapter to mate up cooler to hose.

Really beautiful job your doing. This is coming out awesome.

Beautiful work Tom.
Looking great !

Tom, you should be very proud of the way your car is turning out.

Some more progress on the engine. Installed the oil scavenge line. I plan to run this over the rear of the engine/transmission to the external t-stat much like the early 911. I also installed the RHS heat exchanger. Thank you, Ben McFarland, for the beautiful workmanship on the heat exchangers and for the oil line hardware and plumbing suggestions.

Currently waiting for an M30 X AN12 adapter to connect the CSF cooler to the tank. Once I have that line insulated and in place, I will install the LHS heat exchanger.

[Tom1394racing]

The M30 X AN12 adaptor arrived yesterday. I installed it along with the insulated portion of the cooler to tank oil line. Heat exchangers went on very nicely.

Next up will be the shroud, alternator, fan, wiring harness and carbs.

[Tom1394racing]

More progress on the engine. I cleaned up an old 3.2 engine shroud and installed it along with the PMO intake manifolds. I then assembled the fan/alternator assembly and installed it while making the alternator connections from the Restoration Design new engine wiring harness.

Man those heat exchangers came from me? Must have been 3.5 ish years ago? I can’t recall but I haven’t been involved with any exhaust since January of 21


Looks great

Looks great

I wish you still made them. I need a set or two…..

I picked those up from a want to buy ad that I posted on the forum. One of our members had a set that he hadn’t used. They were perfect for this project, beautifully made and fit nicely.

Oh yes that’s right.

I am positive some has the patterns and designs and could make them but unfortunately not me and I refuse to send buyers to that group of people.

I went to install the lower spark plugs and ran into a couple of issues.

The heads were machined for twin plug but the clearances on the lower holes are too small to allow a regular spark plug and plug socket to fit. I recalled that I had run into this same problem when I built my RSR twin plug engine almost 20 years ago. The solution turned out to be a motorcycle plug with a 16 mm ATF hex and a 16 mm plug socket. In addition, I had open up some clearance access on # 4 lower plug hole by modifying the chain box. All good there now...lower plugs installed.

In the process of scoping out this issue, I had to remove the lower valve covers to check out the lower plug holes. I found that valve covers would not clear the heater exchanger boxes unless I removed two of the lower valve cover studs. This will be a PIA when doing valve adjustments. I think one possible solution would be to use 8 mm bolts rather than studs and nuts for the bottom of lower valve covers. Anyone ever run into this?

This is a pretty typical issue from what I've heard. I think you can get away with milling down just one corner of the covers. See this post:

In order to move forward with the engine sheet metal and the clutch system, it was time to move the engine from the stand to the lift table that I will be using for the engine install. Since I use my two post lift to transfer the engine to the lift table, I took the opportunity to install the roller wheels and tires and move the 914 from the lift and into the daylight for some pics.
