|
|
Doing a 2.5 DOHC swap from a 97 Subaru into an 84 1.9 Westy. Car was purchased from copart as it hit a curb and mangled the front left suspension. Only 120k on vehicle and got it for $300!
Already have the RMW kit, sending harness to Jeff R. and initial plans were to do timing belt, water pump, seals and MLS head gaskets.
Do I plan on doing rings? Read a lot about these conversions sucking oil after the install. Some say to do rings, others to just run it and deal with some oil consumption.
I am having a VW Master Tech assist with the conversion (mainly as he has a lift at his house and I can't tie one up at my work for a few weeks). He is going to do a leak down and pull the valve cover to check the condition of the heads for regular oil changes (seems to be the best indicator of stuck oil rings). Something tells me that a car with only 120k that was totalled with full coverage likely had regular oil changes.
Any advise from other 2.5 swaps? Regrets? Can the rings be changed without splitting the block?
Thanks!
Jason

$300 for a 120k Westy is kind of an incredible find. You are lucky. And good luck on the front end repair. EJ25 has an appetite for oil, you should do whatever you can to make sure the rings are good. At the very least look at the rings that you have. _________________

The Subaru was $300, Westy was a tad bit more!
The 1.9 has been pretty solid runner the last 2 years and never left us stranded, but I am at the point I am done throwing money at it. The mileage is unknown, it is a VW Canada rebuild and has a variety of minor oil leaks, Cylinder #3 is dropping compression and I want something to get me over the Appalachians more than 40 mph.
Once the head comes off, it will give me a better idea of what to do. |

You don't need to split the block to remove the pistons to replace the rings. There are plugs that are unbolted and you can drive out the wrist pin for the piston on the opposite side of the same bank with a 1/4" metal rod easily.

I would probably rering a EJ25 prior to intalling it |

Syncrodoka, I saw that video this afternoon as well, thanks! I am going to do the rings and get a build thread going.
The cost of cutting a small corner after going this far isn't worth it. |

Always re-ring. I made a piston pin puller tool out of a long bolt tap, tap they come out easy. Spin the crank and pistons all pop out.
Rings always get caked in on these motors, they run tight tolerances. _________________ If happiness is being a mechanic, owning a Vanagon is nirvana.

Thanks vanonimous! I will be replacing the rings after seeing how the case doesn't have to be split. |

So I am not sure how long ago you bought this kit. Very recently we switched some parts around to better accommodate the DOHC engine.
Let's get them swapped out for you while your parts are still new. We need to swap out the heat shield and the Passenger side header piece, the header that leads into the 120 degree bend. Please email us direct at [email protected] to arrange the transfer and mention that you want to upgrade for the DOHC parts. There is no cost on the parts and I am happy to share the shipping.
Thanks so much for the business.
