wondering..... (brainfart)

could your ecu have been bad... ??? not horribly bad, just bad when switching???

Doesn't matter now that you have replaced it.

I has been a while....... the engine has finally been torn down to the last nut and bolt. The good news is all the bearings show little or no sign of wear (YEAH!), the oil pump, and housing also show no sign of wear(YEAH!), and the final bit of good news is the timing chain, and tensioners show only...

2 down... 2 to go....

more to come......

and so it begins.... biggest thing on a Blacktop head is core shift... you can kind of see it in top photo's short radius as it isn't centered http://ost.ebeans.ch/albums/userpics/10005/intake_ports_2_panel~0.jpg Chamber #2 on top, chamber #1 on the bottom....

the head came back pretty clean... This was the first 20V head I spent any time on deburring the casting flash http://ost.ebeans.ch/albums/userpics/10005/deburred_casting.jpg Most of the casting flash was around the spark plug tube supports, and in the end areas. Some of the area are purposefully ca...

Nicely done! I always thought the manufacturers should have used threaded fitting instead of pressed-in tubes. Not that I've had issues with Toyotas in the area, but I've had problems with many other manufacturers, especially German autos. @$!?)*$# Volkswagen! along those lines... German Fords too....

Nice product!

I'd recommend keeping that much rotation...

I'll wait..... .0105" / .0175" within .005" so .26mm / .44mm I never realized how BIG the valve clearance where on the 20v ! If I may ask, why did you choose the Toyota specs (.015" to .020") over the Kelford specs (.30mm so .012") on the exhaust side ? Or maybe it's a...

Seem to be still available... I'd contact Robert Crosbie aka https://etsuryu.com/

Now this is a development..... About the time the engine arrived, I was still working on a transmission solution. The easy answer appeared again on Yahoo Japan... https://page.auctions.yahoo.co.jp/jp/auction/m54403331 http://ost.ebeans.ch/albums/userpics/10005/transmission_A340E_for_5V-EU.jpg It is ...

The gaskets have arrived, I'll be laying them up on the block and intake manifold in the next day or 2 to make sure it all lines up. Still don't have timing cover, or water pump gaskets - I'll be concerned about that later if I need too. In the mean time I've been thinking about the ignition system ...

20V shim tolerances are pretty bad. I've now had new, as well as old shims, and in some cases the shims vary by as much as .001" (up to as much as +, or - .0005" either way). I have purchased shims now from a supplier here in the USA, as well as directly from Japan. http://ost.ebeans.ch/al...

I'm in need a "new" seat belt for Surreptitious, mine is beginning to fray......



I'm looking for a driver sidde seat belt assembly as seen in above scan

Get in touch......

For all the 16v heads you've done, I can imagine that the 16v bank is more than double the size of the 20v bank there :idea: actually I have more than double of my total of 20V shims in 3.00mm 16V shims alone :o Dan, do you have the dimensions (preferably in mm) of the (lash cap) shims ? If I'm not...

Well... as I expand to include more 20V head work, I'll need to expand my shim bank. Here are about 3 heads worth of shims http://ost.ebeans.ch/albums/userpics/10005/shim_bank1.jpg Up until recently I kept all the 20V shims in a tiny ziplock bag... but with more use, it just doesn't pay to measure a...

I can build one for you.... message me, or email me so we can discuss it further.

I want to thank Robert(and his wife), owner of https://etsuryu.com/. His help in this project has been immense, from helping me find this engine, to helping me secure the starter, and the service manual, to now saving me a great deal of time, and frustration.
