Maybe I missed it, but I'm surprised you haven't mentioned Alderman... won the Daytona I think in 1980?... long time ago. He was just a local mechanic who was an instant Z enthusiast in the state of Delaware over here (yeah, same state Biden is from). You mention all the famous drivers... but it might be worth mentioning the corner mechanic turned racer success story. He didn't race at that level for long, but he ended up building a Datsun/Nissan dealership that did very well. I went to school with his son... and one of his mechanics (Z enthusiast) lived across the street. Thru all this influence we caught that enthusiasm. My first car was a mustang, but my little brother got a 240 Z and ended up putting a 300 Z engine in it... he loved to say that it had a higher power to weight ratio than a lamborghini... and BOY was it fun to drive. I helped him of course... and we remember those days fondly (late 80s). Thanks for bringing back some memories and for sharing your Z journey.
A gasket is not required for the chain tensioner, hence why you didn't find one in the kit. More important than anything behind the front cover is to ensure the tensioner is bottomed out and the chain makes a nice arc all the way up touching the pass side chain guide. Last note, the oil slinger for the crank isn't required either and has been known to cause loose crank dampers as it acts like a poorly designed washer which can loosen up the crank bolt on high output/high revving L series motors.
Hi Jeff. I just saw you cut out the gasket. Normally you cut an oversize one an then put it on the part and tap around with a small hammer on all the edges. Then you get a perfect fit gasket every time and very fast. It is also working for the holes in the gaskets.
Hey Jeff! Just discovered your channel yesterday and binge watched this whole series. Great work, can't wait to see the car up and running. A cleanly built Z is my dream car so it's been really interesting to see the build.
You also should have purchased a water pump with the large cast iron impeller. The stamped one you installed doesn't fill out the front cover pump galley enough and flow poorly compared to the OEM cast design. Another item of importance is to ensure the oil pump spindle doesn't move up or down more than a millimeter when installed or that the spindle doesn't rotate excessively and sits snug. Both these have been known to cause erratic and inaccurate ignition timing issues. On some high output L motors these issues have lead to disastrous results when being tuned, raced, and dyno tested.
Hi Jeff, just found your channel through a Facebook video. Binge watched the whole of this build so far and love it! What a fantastic job you’ve done so far and so well documented for the cars eventual owner. The rocker cover looks a bit cross hatched on video, is it quite even irl? I’ve heard wrinkle paint is sensitive to how thick it’s painted on but I’ve always wanted to have a go!
Performance cam grind . No relationship with standard factory marks. Adjustable top sprocket required to dial cam in to the cams specs. Need absolute true TDC as a first step. Degree wheel and dial indicators to set up. We will see.
yes yes yes and yes . 2 hours setting up my first one,Adjustable top sprocket makes it so easy when hot try using a straight edge like a ruler on the rear valve spring retainers, closed and on over lap for a quick adjustment. when it gets hot the valve clearance will open up and the lash pads will fall out anyway ; /
Did the first XU1's run Webers at Bathurst Mrs Jeff or the side draft Stromberg's they came standard with. I'm only asking the question because I really don't know. Love ya work Jeff
I did some research from a guy who actually worked on Torana & Falcon Heads for Bathurst cars & he confirmed that they did in fact run triple Webers on the XU1's but because of Group C rules at the time they had to run manufacturers specifications with 3 single throats so the webers were blocked on the second throat to compensate for the anomaly. It still gave them bigger throats to work with & a better carby. The things you learn. Thanks for bring that up Mrs Jeff.
Crossing my fingers, I have never had a performance cam line up with std timing marks and the harmonic balancer can be up to 5 deg out on that timing plate. Its the difference between a dog engine and a good one with the same camshaft with your triple carbys etc,it should fry a std clutch in 3rd,4th &5th
Hey Jeff there is a page on facebook full of l series enthusiast called the "Church of L Series" often come in clutch (no pun intended) when you have a question . :)
For the love of everything, think before you speak. The constant uuhh’s are a massive annoyance compared to the brilliant content you have! It’s much more enjoyable when you know what you want to say (timing chain in this video)

Beautiful watching the heart of the build come together. Can’t wait to see the paint!

That is a great method. I will use that next time.
always good to see your progress Jeff, its coming together nicely

I can't wait to see this beast in action
awesome channel, keep up the good work!!
Yes!! Great job.I feel like it’s a race to who will start their engine first lol
Nice work, mate!

anyone knows the bolt size for both chain guides?

They have a bit of a pattern at some angles, but it looks good.
Can't wait to see whether you go for single/multiple carbys or perhaps a Multi intake fuel injected setup. (ITB's)....and maybe electronic ignition?
I already have the triple OER carbs for it.
Impressive!
teach more how to get more power on L28
No gasket needed for the tensioner. Nissan stopped supplying as it wasn’t needed.

Nice work Jeff, that motor looks sweet. Now if only your porker had a motor....
It's coming...slowly.

We will see. I tried it on 1 2 and 3 on the sprocket, and 2 and 3 had the timing far more advanced. On 1 it was dead on 0.
robwhite240z it’s not a performance cam, it’s the original cam, reground.
