Are the wheels I have weird in some way? on to the other issues... If the car was sitting a long time is it not possible your hydraulic valve lifters are not pressurized as well. I don't know what the fix for repressurizing them is, but I've heard of this effect before. There should be posts on the board about it. Again, I don't know if this could lead to 0 pressure in a compression test... Definitely soaking the rings will be required though. If the head is toast I would look at rebuilding it unless you know where you can get one off a junker R. Come to think of it I am not sure the heads are different from a regular head... maybe different cam? I don't know. I thought the main difference between the R engine and the others was in the bottom end and in the turbo... Still rebuilding is still a pretty solid option unless it's completely destroyed. Some would argue you're better off with a rebuilt head than a used one anyway due to all the nice cleaning and polishing and bearing/sleeve replacement they can do in there. Depends on what condition the cams are in maybe? I'm just thinking out loud, but I can't help but weigh in - the idea of getting an R for a song is so cool! -- 1998 V70 AWD Turbo 190k+ Mark this post as an answer to my question<- Use this feature to mark quality replies to your post.
