Default Leaking exhaust valves...how long till it blows

I have leaking exhaust valves in cylinder 2. Roughly half of the pressure as the other cylinders.
How long do you this will last if it drive it easy?
Check engine light has been on for like 500 miles.

My guess is random misfire or roughness.

It’s the misfire code for cylinder 2. I would also get the random all cylinder misfire code. Got it checked out in may or so, and they did the compression test. Told me not to drive it until I get a new engine. New iag 600 long block has now shipped and I decided to start driving it again, just wondering if it’s likely to blow up immediately or not. Do you think if it blows it going to wreck something non long block? I got a new fp red and the 600 going in.

I also get cylinder 2 roughness at max 60 if I idle. If I just drive it around it might do 60 for like 1 second, once.

I would not drive it especially if you plan on reusing those heads.

I would try to save the block and work on it on the side when the IAG one is in as a project. Then when finished you learned how to build a block and have a back up when the IAG blows.

2 year 24,000 mile warranty and I hate wrenching with a passion. I find nothing more frustrating.

Man that long block is crazy price. I rebuilt my heads and my block and used a little better piston and rods then the ones in that block and was about $6000. Parts and machine work.

Lol. labour is what is cheap in this game. $9,000 engine, $3,000 labour. most people will easily save money by getting it professionally installed the first time instead of destroying new parts, wrecking others in the progress, buying tools, etc. its waaaay cheaper to take it to the shop. and with a warranty on the engine, its like... wayyyy cheaper.

unless your a certified mechanic, i wouldnt advise you install anything more than a cat back and change your own air filter on.

I agree, but I said to work on the stock block when the IAG is installed. Good luck with the IAG block.

Subaru engines In my opinion are some of the easiest engines to pull, and a hoist cost $200. Ive rebuilt more then I can count Subaru motors and never went to school or have any certification's. You just have to be real meticulous with your work and triple check everything. And the only real specialty tools that are necessary is a bore gauge and a set of calibers. Oh and have a good machine shop.
