Mrs. Brucey can inspect to see if you have a bug up there,...and extract it with a birds foot.So I didn't do any of that.
I went to a friend who I borrow cameras off of for Youtube and asked if he had a bore scope.
We call it a butt hole camera.
that deserves a link from South Park.After much searching I haven't been able to find Lemmiwinks.
Definitely an interference engine has many members have found out the hard way!I'm going for the crank pulley being out of position or some other cause of the timing being off. I understand that this engine is non-interference so bent valves in every cylinder is extremely unlikely.
Just about anything can be done! But what counts is the degree of difficulty to get it done . . . 🙄Sadly no. I was mostly joking about H6 it's a nightmare but it can be done.
UPDATE AS OF JANUARY 2021. Unfortunately iWire is no longer building harnesses for standalone ECUs to focus on stock ECU applications. Although some people have made it work with the stock 6 cylinder ECU there are a number of issues that exist with this route and that we are currently unable to...www.iwireservices.com
And they come in real handy for many applications where you can't get your head into-or don't want it burnt.
Well we'll find out tomorrow. I'm going to finally buy an engine stand and take the heads off tomorrow and go from there.@Brucey
I've been through some of this. I have some of my own images from a borescope/endoscope that look similar. I had zero compression on cylinder #4, and another that was a little low. I rotated the scope and saw a shiny spot that looked like a crack, but was really where the exhaust valve hit the piston. Yes, an engine with one bad cylinder will run, but not well. I disassembled the engine and found that the exhaust valves were stuck open (bent), but were also coked up with burnt oil like the cylinder. So the exhaust valves and cylinder had seen a lot of oil and eventually stopped moving, which caused the piston to strike them. The timing on my engine was fine, so a different scenario really. But it does look like the spark plugs needed to be replaced in your engine or the PCV system was drawing a lot of liquid oil into the engine as happened in my case. If the head gasket had gone, the pistons get nice and clean from the steam (depending on the gasket failure mode). In the photo below, the strike point is very reflective, and the clean piston portion is from the fuel mixture washing the piston off as the exhaust valve was always open. View attachment 500904
You say that because of the pictures? I thought that was the piston top with 2 valve - formed dimples in it. Could be a valve showing there I suppose, but hard to tell because there's nothing to scale it by . I thought it was the piston top.The key is the valves that are not closing and appear to be off center - no way they would seal.
I was told the vehicle had 'snapped a timing belt' but when I got into it the belt was intact but had walked off of the upper left idler and burst through the cover.
Bent all 16 valves when lost timing belt on 05 outback with manual. Wife coasted to stop after broke with clutch engaged turning over engine did a nice job to them all.
Tensioner was also not correctly functioning. After retiming it and installing a new tensioner I did a compression check.
I figured when I bought it I needed new valves or just a redone head and call it a day.
But I showed 0 psi on all 4 cylinders.
Thinking my old compression gauge had broke (o ring crumbled) I bought a new one.
I was told that this isn't likely but I don't see how it isn't knowing the circumstances.
So I guess I'm just looking for a second opinion other than my own here?
I was planning on deciding whether to rebuild or salvage. I will probably have the heads decked as a precaution.I'm betting nearly all the valves are bent (or at least several per cylinder). I buy up cheap used Subarus with this issue regularly. They don't always bend all the valves, but sometimes they do. I've repaired them using used heads from a u-pull-it yard, and I've used new valves. Depending on how many valves were bent. Since you already got the timing gear, and the engine is out, it is a great time to reseal it and make it good to go for another 75-100k miles.. You are well on your way to making it happen, and it is a really good looking setup.
