Tony_de_whitt Posted March 12, 2016 Share Posted March 12, 2016 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 Quote Link to comment Share on other sites More sharing options...
AdventureSubaru Posted March 12, 2016 Share Posted March 12, 2016 They are interchangeable along with their corresponding brackets. All things being equal - the two bolt style is less prone to failure. Sounds like it's also the newer part of the two. Quote Link to comment Share on other sites More sharing options...

Tony_de_whitt Posted March 14, 2016 Author Share Posted March 14, 2016 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.

lmdew Posted March 14, 2016 Share Posted March 14, 2016 Yes, the double exhaust ports. The 96-98 2.2 have a Single port exhaust. Quote Link to comment Share on other sites More sharing options...
Tony_de_whitt Posted March 17, 2016 Author Share Posted March 17, 2016 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 Quote Link to comment Share on other sites More sharing options...

kamesama980 Posted March 17, 2016 Share Posted March 17, 2016 Ok Embarrassing moment over. I haven't put new plugs in yet ☺️ That was my thought. Big sigh of relief after you realized that, eh? Quote Link to comment Share on other sites More sharing options...
Tony_de_whitt Posted March 18, 2016 Author Share Posted March 18, 2016 Yes was pretty funny just didn't feel right.lol Ok I've got the plugs BkR6E11 NGK Do we run the 1.1 gap they are set at for this frankenmotor I'm sure I read smaller.??

Tony_de_whitt Posted April 11, 2016 Author Share Posted April 11, 2016 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 Quote Link to comment Share on other sites More sharing options...
Tony_de_whitt Posted April 11, 2016 Author Share Posted April 11, 2016 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 Quote Link to comment Share on other sites More sharing options...
