The cogged idler pulley at the bottom, right side of the picture (left side of engine) - the bolt mounting its idler bearing is supposed to be, uh, centered in it. The seal failed and/or the grease ran out, the bearings failed and escaped, the pulley went lopsided and flapped around, miraculously the engine did not jump timing. e: enourmo, I completely agree, but this is far from the first time I've heard of this exact thing happening on an EJ25/EJ22. In fact it happened to Terrible Robot a while ago, because the seller said "timing belt done!" but was a cheap fuckass and didn't do anything else at the same time.

I had that pulley let go on the forester (several years and another engine ago) and when it did it shot all the ball bearings out like a goddamned claymore, perforating the timing belt cover and one somehow ended up busting the rear housing on the driver's side foglight  Threw a new pulley and belt at it and drove it on that engine for another 20k miles.

About 3 years old but this happened to me 3 hours out of town, never figured out whether the timing did jump or it was just CIS playing up from the cold weather but I managed to drive it back home while running like complete poo poo at idle. Lesson learned, always check the timing belt before buying a vehicle and driving it for a weekend out of town.

Big Daddy Keynes posted:Triggered by the mention of jis right now so many stripped threads. Literally shaking right now. I thought JIS threads were just metric and that it was only the head size (on hex bolts) and cross shape (on phillips/jis heads) that was different? I know the JIS bolts on AX15s/R15x transmissions are just M10x1.25 thread with a 14mm head instead of something larger that meets the ISO/Deutsche/ANSI standards, but admittedly I do very little with metric unless I can't avoid it.

The only difference is in the philips heads AFAIK. Hex bolts come in all kinds of shapes and sizes with seemingly little relation between the size of the hex head and the footprint, it just seems to be whatever the designer felt like at the time.

Well, there are at least four standards: https://www.boltdepot.com/fastener-information/Bolts/Metric-Bolt-Head-Size.aspx ANSI/ISO, DIN, JIS, and DIN/ISO Heavy Hex. MOST bolts I've seen match either ANSI/ISO or JIS, at least on vehicles I see in the US, with parts sourced from US and japanese manufacturers. I've not worked on anything of german origin but I bet their bolts tend to follow ANSI/ISO or DIN specs. There are always exceptions, like reduced-head fasteners (may they rot in hell) or the true bastard poo poo like the metric-head, SAE-thread (or vise versa, I can never remember) fasteners used on some eras of Land Rover engines because BMW got involved and someone wanted to keep someone's assembly line tooling while using someone else's machine shop tooling. As usual, in engineering - standards are awesome... because there are so many to choose from! The fun part is that the standards MOSTLY agree, on small and large fasteners, with the medium size ones everyone actually uses being the points of contention. They only really disagree on what head size an M7 (only exists in DIN), M8 (JIS uses a smaller head), and M10-M18 use. Everyone agrees on M4, M5, M6, and M20. e: the best part of this is that you can probably reasonably reliably use that chart and the fastener/thread sizes on a component from your vehicle to determine what nation was calling the shots when that part was designed. I bet DaimlerChrysler era designed portions of jeeps (545RFE transmissions, WJ and late TJ steering boxes, etc) use DIN or ANSI/ISO metric fasteners, I know for a fact that Aisin transmissions used in jeeps are almost 100% JIS, and most of the engine compartment fasteners on an XJ that are metric are ANSI/ISO. Most, but not all - for example the M10 starter bolt is a 15mm head, which complies with precisely zero of the standards, even though it goes into a Nippon Denso starter, and most of the bolts holding an NP231 together are 15mm head 10mm thread, which also doesn't comply. kastein fucked around with this message at 05:09 on Oct 22, 2015 |

That came up quite a bit when I worked at the shithole tranny shop, we had a policy of always replace all bellhousing bolts but we got our bolts from a DIN-compliant company, and Freightliner uses those special snowflake 15mm headed 10mm bolts on some medium duty bell housings. Hell is trying to tighten a dozen 17mm head bolts in reliefs meant for 15s with severely limited access to about half of them.

Right. I should have known that. I just dealt with it on a Subaru Forester. Note how the stud is not even there. I had to replace the water pump just to have threads for the new one. Mine did the melt-the-timing-cover-and-depart-the-vehicle all 16 valves bent. Replaced them, did the headgaskets, new timing cover and it's back on the road.

Boxer engines seem like such a good idea in theory, what with being balanced and smooth and all, but it seems the implementation always sucks. Inline 4s may vibrate, but they don't (often) do that kind of poo poo.

A boxer engine is only acceptable in an air cooled application with timing gears. Also, every Subaru I have ever heard sounds like a bug with a dead cylinder.

I'm not sure, I've run a bug with a missing spark plug and it definitely changes the character. I also (tried) to run one with the plug wires out of order. I was a teenager, skipped over that part of the manual. Being told that firing order was important was quite a revelation.

It actually still drove and a few new idlers and a belt later, plus some duct tape over the hole, and it was back on the road. Also the older sohc motors were non-interference.

Besides the porosity of the aluminium, I thought the EA81 was a good boxer. OHV so no complex timing belt and the pushrods contained within so not a huge amount of pushrod tube O rings to leak. I mean it's nothing special but as an engine it worked well.

I never have much to post on this thread since A. I own a lovely flip phone after breaking/loosing so many fancy ones and B. very little shocks me any more. But today a 1992 Corsica earned a high score in brake and owner degradation. "Can you check my brakes? They are making a noise" Classic. The dude managed to grind through the entire front plate of his left front rotor and continued on grinding past the vent ridges which im sure didnt make any noise at all, and then proceed to grind through the back half of the rotor surface to the point it remained a thin sliver of a rotor a verified .064 of an inch thick. The piston was of course completely out of its socket lodged in the carrier bracket keeping pressure on the outer metal pad that was still sawing away with brake fluid everywhere. Im gonna try to get some pics off my lovely flip phone but i need to find drivers for whatever phone this is. It just has an att logo on it. Does att make phones now?
