Not good

Pretty much what I suspected
but fed up all the same


Type4 2.0FI

Valve gaps are still spot on since I last did them so I guess standard overheat/rings, barrel on 3.
Choices
Quick motor out and repair whatever I find.
Full rebuild of the original engine that I've got in bits in several boxes.
Subaru self conversion!

 

I'll guess at a cracked head - valve blow past.

Try a leak down test if you have/can borrow the kit.

 

It's a good shout, would be handy as I've got spare heads.
Engine out weds I think.

 

Oh no

Good luck, at least you have the ability to sort out whatever you find........or self scooby.

You may as well mend that one for now, keeps you on the rd and if you decide to go scooby you can sell the Type 4 as a working engine.

 

Right, spare afternoon, let's get this lump out

 

Is it out yet? Come on, it's only 4 bolts!!!

 

Feel free to give opinions




Had to leave it at that for today, run out of time.
No cracks in head
Obviously running rich which being FI is not so easy to fix
Will take barrel off 3 tomorrow and check rings.

 

Running rich is easy to fix, just adjust the mixture, looks like a blown gas ring perhaps ( head gasket), check if it has them, pictures are poop

 

Is the inlet valve seating correctly? I might be wrong but it looks to be pushed open slightly? Can you compress it and check around the edge to see if it's seating, or if anything has blown past it whilst closed?

 

Easy for you, you've got a gas analyser!

 

Hope it's just a worn ring summin daft Iv never wanted to do mine

 

Iv an old exhaust aniliser u can use dunc if u want me to post it up @pkrboo had it for a while not sure if it was any good but can drop it to techenders if it helps after ur done

Well the only thing I've found that might have caused low compression was a dodgy spark plug thread, very close to giving up its plug. Valves seem ok so do rings/barrels.
Anyway, chose the best looking of spare pair of heads which had the tapped hole for the ts2, cleaned it up, lapped valves, spent a few hours trying to remove broken exchanger stud , finally drilled it out and tapped for a new one.
Cleaned lots of bits ready for refit tomorrow
Fingers crossed!
Trying to keep it going for minimum cost at the moment, going to rebuild original engine later in the year.

 

Hasn't everyone

 

You can mend it Mr Flake
No need for the Subaru engine .....that's dark stay away from that!
Come back into the light

 

All back together and running at full power again

So much better , I might do the other head when I take it back out soon to change the gearbox!
