#1552504 Oil and oil filter suggestions for '73 620?

Tis but a scratch.....

A little sand paper, and it will be good to go  :)

#1552501 The turbo.........does not fit............

Posted by G-Duax on 20 March 2018 - 06:42 AM

Remote mount turbos are problematic at best.

Too much heat loss in exhaust flow before it gets to the turbo.

Way more lag.

Plumbing lube oil to, and from the turbo, which requires an axillary pump to push the oil back to the engine.

Plumbing charge air all the way back to the engine.

A smaller turbo, and a GOOD heat shield.

Not some single layer shield.


I once had a header way to close to something in a '76 Corolla, but made a multi-layer shield.

Several layers of sheet aluminum (stainless would be better), with fiberglass mat sandwiched between them. 

All pop-riveted together.

Worked great.

Do not use Fram filters


Fram should pay people the cost of replacing their engine ahead of time....

For many years I used Fram filters, with no issues until the mid-'90s when I put one on a high performance engine.

Filter collapsed, sending debris into every critical point in the first 2-3 days.

About that time, I searched the 'net for info, and found out that their products had turn to dog dodo.

Never again !


Funny thing on oil......

When I had went back to school in the early '80s, I was driving a $50 Vega, that passed oil out the tail pipe quicker than a storm drain.

I was taking other people's drain oil, used cooking oil, even gear oil to keep it running without eating into my meager finances.

It kept chugging away until I finished school........:)

Dead white is too lean, or too hot of a plug.

Call us back when you burn a hole through the piston.

A flip-up rear sight is best used with a flip-up front sight.... :D

#1551843 H190 510 wagon axle end play; what parts wedge bearing in place?

Posted by G-Duax on 16 March 2018 - 08:21 AM

My 510 wagon had ball bearings, as do most Nissan car solid axle set-ups, including the Cedric, and Gloria H190s.

The only Nissans I've seen with tapered bearings are the trucks.

You might have really worn bearings.

I thought pulling plug wires on a running engine was supposed to be done by your wife....

#1551211 Electric power steering ?

Posted by G-Duax on 13 March 2018 - 06:48 AM


Have seen other motor driven PS units, but never seen one with a stand alone electronic module.


I had no reason to change the rack on my Cressida, but wanted to dump the stock belt driven pump, but because of a 2:1 steering quickener, still required power steering. So the Toyota MR-S electric pump fit the bill.




It has all minimum required electronics built into it, like automatic digressing power assist, that the faster the vehicle speed, the less assist it gives, on a linear rate. 

And someone has come up with a $65 plug-in module that gives you the ability to program the assist rate.

All it needs is hoses to my rack, switched electrical power, and a speed sensor input.

#1551027 Help! Flywheel Ring Gear pull through bottom or top?

Posted by G-Duax on 12 March 2018 - 09:53 AM

Could be the bendix on the starter.

When you pull the starter to test it, make sure the little gear on the starter jumps out to as to engage the ring gear.

If it doesn't, then the bendix is sticking.

Sometimes they can be lubed, and they will work fine.


When you look at the ring gear, minor damage, and flakes of metal are the result of the bendix not properly engaging the ring gear.

With a new starter, a slightly damaged ring gear will still work fine for many years.

 I finally feel like I should get one, but have very little experience in building cars.


Before you throw $$ away, and get in over your head, take some basic auto repair classes at a local vocational school.

Start amassing tools, as nothing screws up a car as much as trying to work on something without having the correct tools to work with.

#1550522 Datsun 1500 (620) exhaust system

Posted by G-Duax on 09 March 2018 - 03:41 PM

Doubtful, but check eBay, or dealers in Greece.

I've seen a lot of Datsun stuff coming out of there lately.


But you will probably have to have something made at an exhaust shop.

Most of those 10/22 full auto conversions turn out to be hack jobs on the safety lever allowing it to be rotated counter to the normal motion and this is a disaster in the waiting.  File too much, fail.  File too little, fail.  How many safety levers does it take to make an illegal conversion?


Not talking about illegal hack jobs....

Talking about conversions by licensed class-3 manufactures, and legal purchase with a class-3 tax stamp.


Quality conversions have a lot of machine work, and a lot of new & additional parts.

'Crap' = something unexpectedly broke.


'What the F*** ?' = Something I did failed.
