Ej22 heads ej25 block help needed


Recommended Posts

Hello folks

 

Looking for some advice/ opinions

 

Attempting a frankenmotor.

 

1997 outback dohc ej25

1993 ej22 heads

 

Nearing stage of re assembling engine.

 

Which tensioner set up should I use on the re assemble.

 

The ej25 had the single bolt tensioner and the ej22 had the double bolt tensioner.

 

I'm swaying towards using the tensioner I got with the timing belt kit which is the 2 bolt set up.

 

Anyone got any opinions on this??

 

Thx

Anthony

Another question. Possibly a stupid question.

 

As I said I'm doing the frankenmotor thing and have been doing a fair bit of reading.

 

One of the things I've read is that there are 2 types of ej22 heads??

 

And that only one type will work.

 

The twin port is the one to use apparently.

 

Does the twin port relate to the twin outlet for the exhaust???

 

As I've never seen an ej22 with a single exhaust outlet.

 

Thx

Thx

 

The engine the heads came off were from a 1993 liberty or legacy Australian spec.

 

They are twin port though.

 

Ok I've just put the heads back on and timing belt. All the notches lined up etc and seems good.

 

Is it normal to not feel the compression on these engines??

 

It does stiffen up when turning it over but doesn't feel the same as other engines I've done before just wondering if the hydrolic valves changed anything or it could be in using a 2 foot bar to turn it over with.

 

Just thought it would be harder to turn over. New rings. Pistons and heads reconditioned.

 

Any thoughts

 

Thx in advance

Ok

 

Things moved on but not as I would have liked.

 

Got it all together installed. Running.

 

Wasn't totally convinced all good as tapping noise.

 

Didn't sound right

 

Any way test drive lasted about 30 mins. Then I got towed home

 

Only had time for a quick look. Sounds like no compression so thought timing belt slipped.

 

Engine will turn but doesn't feel right.

 

The cam sprockets on both heads appear to be jammed solid.

 

Maybe I should stick to carpentry ????

 

Any thoughts??

Thx in advance

Ok had another look.

 

Engine back out.

 

Looks like the left hand head has jammed solid.

 

The timing belt is all torn and wedged under the belt guide.

 

The inside of the rocker cover one side looks very dry and I'm suspecting has had no oil.

 

Not too sure though.

 

Need to try and find the cause and hope no internal damage.

 

Any thoughts thx
