Good work max.
Great job Matt - really interesting to follow the thread. Ever thought you might be doing the wrong job?
Thanks for the comments guys
Ever thought you might be doing the wrong job?
Made some more headway today, attacked the cylinder air guides with Nitromors and then bead blaster:
Painted them with Tetrosyl VHT paint and baked in the oven for 1 hour @ 250 deg C to cure (.....kitchen still smells a bit )
Got a few more of the case odds and ends fitted and then started on the cylinders. Checked all rings gaps with new rings - all to spec, then assmebled the pistons into the cylinders on the bench.
ARP head studs fitted:
First piston & cylinder on:
Remaining cylinders on and starting to look like an engine again
Finished the cylinder heads today - new valves and springs fitted - spring lengths set:
Air guides installed and heads loosely assembled onto engine:
First cam carrier on:
Realised I've missed a sheared M6 bolt on the left cam carrier so progress on hold until I get this out.
Sheared bolt removed from cam carrier so both carriers now torqued down to the heads with loctite 574 to seal. ARP head nuts also torqued up. Cams installed and turn fine.
Hoping to set the cam timing at the weekend so started investigating cam locking tool options (Porsche tool P237). Spoke to a independent specialist to see if they'd lend me theirs and was surprised (& alarmed) to find out they didn't have one but use an impact wrench to tighten... Then tried my local OPC (just for a laugh) only to be told firmly "we don't do that kind of thing".
So just spend an hour or so with my mini air grinder and a file creating one from a piece of 2" steel tube. Teeth all cut:
The gear even fits !
Just need to weld on the ergonomic hande:
That takes the shortcake biscuit - you are a beaut mate

Specialist I can't believe the to55ers openly admit to that.
All you need are these,
and you can be a Porsche specialist too.
I'll bet you're glad you are doing it yourself.
[Just need to weld on the ergonomic hande:
Spot on Max. A lot neater than my rusty attempt.
Making things like this give plenty satisfaction when you come to use them.
Tackled the cam timing today - all went OK, not something to be rushed though !
Started by double checking the accuracy of the TDC mark by dropping a probe down onto No. 4 piston:
Set the timing using the "clamp in place of tensioner" method as per Wayne Dempsey's book:
Cam gear tool worked really well
Then fitted the tensioners and double checked cam timing on both sides - exactly the same as with the clamps so not sure whther the clamp bit was worth it.
Got a few more bits fitted up - decided the orignal cam oil feed pipes look a bit tired so time to email Tripe....
Need to get all my tinware down to the powder coaters asap.
Gorgeous. I look at this thread and wonder why you are not doing this for a living - better than many 'specialists'.
Thanks John - must admit I wouldn't mind doing another one when I've finished mine.
Didn't have a good week at work so progess has been slow.....
Gave the outside of my rocker covers a bead blast and then air brushed with laquer:
Got some new PRV springs as mine were a little short compared to the spec - was surprised how tired the old springs felt compared to the new ones (new on the left):
Fitted the rest of the rocker shafts and then rocker covers, also the new cam oil lines (thanks Tripe). Almost oil tight now:
Few more bits on today: oil cooler, heat exchangers and solid oil pipe:
Had my first proper look at the inlet manifolds since the porting work. The runners have been cleaned up and opened out slightly:
Main radii have been smoothed & blended. Also removed the casting marks from the main ducts:
Didn't show much of a difference on the flow bench so not expecting any great gains from this...
Gave the manifolds a clean in the dishwasher on the intensive programme - worked a treat
Started building up the inlet system and also installing new seal kits on the injectors:
Now waiting for all the other bits to come back from the powder coaters....
I love the use of domestic appliances
This is just beautiful work. I'm not kidding Matt - best I have seen yet
Top job, very clinical (are you a doctor)
Had mine fired up at the weekend post to follow.
Got everything back from the powder coaters, went for satin black on the tinware:
Fan and shroud are OK, although a bit pitted following the bead blasting...
Got the fan reassembled and Loctited togther:
Finished assembling the fuel & inlet system - was glad I'd taken a few pictures of the nest of hoses, pipes & brackets at the rear before taking apart !
Fan assembly back on the engine:
Going to have to start patching up the rear tinware tomorrow - have put it off as long as I can !
When's it going back in the car?
Looking very nice!
Looks fantastic - exceptional work.
When's it going back in the car?
Thanks - aiming to put it back in the car at Easter then on the road 1st May. Have got quite a few things I want to do on the car before it goes back in:
- new gearbox mount plates
- new / refurb heater boxes
- clean & tidy engine bay
- pressure wash and underbody wax rear bulkead
- refit oil tank
So will be putting a cover over the engine for a couple of weeks while I get this lot done.
There's some very talented folks on this site
'IB Engineering Services' being offered in the future?
Few more bits done: exhaust & airbox on:
While fitting the pre-silencer pipe I noticed the flange holes are a lot smaller than the exits from the H/E and cross over pipe - by >5mm, can't be good for flow:
After some grinding now matched to incoming pipes:
Attacked the rotten rear tinware piece - aiming for the "functional" fix (can't compete with TB's efforts !)
Done - now off to the powder coaters
Also decided I'm not happy with the paint finish on the fan shroud so that's off again and heading back to the powder coaters....
Max lovley work.
What have you held your fan centre on with ? it looks like counter sunk allen bolts ?
Max lovley work.What have you held your fan centre on with ? it looks like counter sunk allen bolts ?
Yes - just M6 stainless countersunk allen screws. I think they were 12mm long - need to be careful as there isn't much clearance to the alternator. Also had to countersink the hub holes to match.
Original rivets are only aluminium so I figured std. stainless screws would be fine.
Everytime I have some fettling thats needed but I can't be bothered, I just look at this thread and get all the enthusiasm back!
Any chance of a picture of the much neglected and little understood (by me at least) rear (or front I guess) of the engine?
