I get the impression that Davin isn’t digging this Type rebuild series. I get it, but also enjoy learning new engines & why engineers did what they did in their design phases. plus, I’m interested in this type engine for a swap into an old underpowered Porsche roadster I drove in High School in the ‘90s. anything boosted via turbo or supercharger has its place in my life these days.

Very well done. You hit alot of topics that are often missed on EJs. I opted for a new shortblock becuase properly repairing an old one is a PIA and with the added cost of maching. I was better off with a new short block for $2200. $3200 with forge pistons and rods which has the best bang for the buck.

Seeing this gave me flashbacks to rebuilding the 1,000 cc engine in my 1966 Beetle. The advantage of that engine was having a local machine shop service the saddles. They machined the case, the cranks and we bought appropriate bearings to reflect that. Pretty quick and simple. I don't envy you this engine.

I rebuilt the motor on my '02 outback. I don't get the hate for these motors displayed below. I myself was intrigued by the quirky design, and I admired how compact the motor was.

I applaud your humility, teachability and perseverance. Several times in this build I was shaking my head watching the videos, but you corrected the vast majority of your mistakes in your subsequent videos. I hope this engine lasts, I couldn't have built it better myself.

Great video again. Greetings from Belfast in Northern Ireland. I love the fact that rather then spend more time running around trying to buy some long-reach circlip pliers you modified the long-nosed pliers. It was probably cheaper the buy a new set of long-nosed pliers, too. Some of our, so called, tradesmen nowadays would never have thought to do that. Keep the videos coming.

Master cylinder snap ring pliers can be useful for deep-set snap rings like this. I ended up needing to buy a pair to, ironically, remove and install a snap ring in a master cylinder.

unwilllingness to use proper machine shop with fixtures to line hone WILL result in early failure. I understand your reluctance in creating new alliances when you are unlikely to do another Subi.

Just remember the Rockauto tip of the day. "Don't forget to install the inside - farthest away from the block hole wrist pin clips. Before you install the pistons..."

You main bearing mismatch reminds me of the Buick 3.0 of the early 1980's. The mains are not in a straight line. At the place I worked, they had one we were replacing rods and mains, in the car. The story goes, finding the proper size bearings was a nightmare. In fact I think after replacing them the motor did not turn. Now the boss being fed up ordered a crankshaft kit and had the block line bored. After getting the block back the crankshaft did not turn again after tightening it down. Lots of phone time with GM we found out you cannot line hone that block, the mains were not straight. Also some of the top and bottom bearing shells were different sizes. When assembling the short block at the factory. They would start with standard bearings. Now if needed they would make, or have, custom halfs to make everything work. Now this information came from GM engineers. If you've ever messed around with one of these 3.0L carburetored motors, they suck!!! Shake and rattle, none of them run smooth. Thank God they were short lived...

What I'm curious about is when you're installing the wrist pin clips, can a clip actually "fall" in between the cylinder and the piston? That would be a nightmare.

Lubricity? First time hearing that word for me sorry. Love the build by the way.

This may have already been stated, but it's my understanding that a sealant needs to be placed between the case halves in a very particular way...at least the repair manual specifies that. Just curious why he didn't do that. Japanese machine surfaces are amazingly precise but it would suck if you put that in your car only to find a leak that requires full teardown to repair.

When the EJ came out it was a world class engine for the Japanese. Far more advanced features than most American engines and on par or beating most other imports. All from a tiny company with less than 1% market share. Toyota sold over twice as many Corollas in in the USA 1990 as Subaru sold cars. The EJ won many races, took many records, was incredibly reliable, and had a lot of positive attributes. There have been issues over the years, but it was overall a very successful platform. Keep in mind they are working on a 20 year old engine now and that it was far cheaper than anything Porsche. :)

Does the number 1 piston have to perfectly level to the top of block on compression stroke to make a TDC or after TDC

Keep doing what you are doing. Maintenance is key. Make sure you change the coolant every 60,000 miles at most too, and keep the cooling system in general in good condition. Always use high quality premium fuel. An air oil separator is one of the best reliability mods with zero downsides. You could look into the cylinder 4 coolant reroute, but jury is out on how necessary and effective it is.

What is this coating on the engine block?

no sealant?

How would you compare rebuilding the Subaru boxer to rebuilding the VW boxer? I would hear some non car guys say "I like Subaru because they got engine ideas from VW." It isn't true, but I don't have a great way of explaining it other than the fact that the VW was air cooled.

@chash7335

VW (Dr Porsche) got their ideas from Dr Ledwinka at Tatra.

In terms of the line hone, if the other journals are smaller, could all of the journals be honed to the same size and use thinner bearing in the center jornals and thicker bearings on the end journals? Are the tolerances such that that sort of action is not possible or is the stress on the journals and/or just outer journals too great for that? Honestly did not know.

@802Garage

Жыл бұрын

According to the Subaru manual, the crank journals are not actually different diameters. The only very slight difference is 0.0001 that's one ten thousandth of an inch of bearing thickness, thinner on bearings #1 and #3. All oil clearances are even listed as the same. Not really sure where the confusion came from unless I'm missing something.

Guess there will be no honing with a torque plate. Sad. Always beats me why people go through all the trouble of stripping down to the block, getting it machined but not doing that
