What Is The Best Engine Degreaser

So my dad ended up deciding that we should buy a 2003 Subaru Outback with the H6. We got it for $2000. It has 94k miles on it. The reason we got it so cheap is the owner was tired of putting money into it. She quit driving it at the end of April this year. She took it in for everything so I have paperwork to follow to see what has happened with it. The last sheet mentioned possible leaking head gasket. I want to clean the engine and engine bay so I can see had bad of an issue this really is because leaking coolant hoses was also mentioned. I am also going to borrow a chemical tester to see if there are combustion gasses in the coolant to confirm bad head gasket. It drives fine so I have a hard time believing head gasket as these engines are not known for head gasket issues.

Thanks for any suggestions,

Looks just like this.

I don’t have an answer for your question, but holy hell, is there actually no rust bubbles around the rear wheel well?!

I think the last time I saw one with no rust was 2003.

These head gaskets leak oil externally, usually at the back corners of the heads/block.

Its not as common as the early EJ25D, as those leaked internally, combustion gasses into coolant.

Lol the car does have a rust spot. It’s in the door jam on the rear driver’s side door. That’s it. The car pictured is not actual car. Same color scheme though.

Get a couple cans; don’t park it on the grass. Warm the engine up a few minutes and spray it, rinse repeat...

Sorry, no suggestions. I just wanted an excuse to post a pic of my car.

Based solely on smell, Simple Green is the best degreaser of all time

I would suspect valve cover gaskets over head gaskets. I always put a piece of cardboard on the ground where I park a subaru.

Ok. I was looking at the picture and was very confused. A rust-free second gen Outback is rarer than a high miles Veyron.

This is an H6 motor not the 4

Lol maybe I can’t read. So just to be clear because I am now thoroughly confused, you were talking about the H6 engine originally? Sorry.

No, the EJ25 4 cylinder. I didn’t see you had the H6 so when I read “Subaru” and “Headgaskets” and saw the image my mind went on cruise control...

Youve never been to Seattle, have you?

Purple power. Or slap some lanolin on there and sit overnight.

Very uncommon for the H6 vehicles to have failed head gaskets.

You guys would love the PNW. Rust free Subarus as far as the eye can see

Lol fair enough.

That’s what I have read on the all knowing internet forums. But there have been some that have failed at this low of mileage. That is why I am a little concerned.

yeah i think we have seen maybe 3 in the year I have worked for Subaru.... I can’t even count how many 4 cyls

What were the symptoms if you can recall of the ones that needed head gaskets? Would checking for combustion gasses be the tell all?

I am not sure, I am in parts so i just see what the vehicle needs, not why they need them. Most of the time they leak externally though.

well, there’s lava, but it’s hard to find fresh lava in your local autoparts store. Check with the lawn and garden centers... and don’t park on the grass when applying
