98 V70 non turbo Oil Pump Replacement - need some help

[abscate]

I guess you can put it back on, reassemble, then do a quick enginevassessment with the new oil pump, idle, oil change to inspect For more pieces, then replace it. If you have the part on hand you can return it if the news is bad?

It’s less than hour to replace and retime with everything apart

Well, here's today's update. After a great deal of effort I got the oil pump off. The matthews volvo site community sort of undersold how hard it is to remove the oil pump. There's not much to pry against. Anyhow I eventually got it out. There's nothing wrong with it. I was shocked by this because I was sure that was the problem.....

In an effort to clean up afterwards with carb cleaner I thoroughly sprayed off everything and notice a big ragged edge on the hole that feeds oil into the oil canister. I wish that I had noticed this earlier but it was difficult due to the oil coverage and my haste to get to Chicago to freeze my a$$ off at the in laws. Apparently this is where the big chunks I found came from. There is also additional deformation and additional cracking in the same location. I looks like it was hit from the other side with a hammer. Anyhow, not good news. I'll post pictures when my phone battery recharges. I'm guessing something failed internally (piston rod?) and punched a hole in the oil pan at that location. Remember, I have a misfire code on #1.

Thoughts? Trying to decide what my options are at this point. At least it wasn't my fault. When it comes to winning lottery's I only win the crap ones, unfortunately.

98v70dad, I think you should go out and buy lottery ticket tonight...LOL.

Joking aside...The only way to find out is to drop the oil pan...vs...junk yard.

Yeah, I'll probably do that (not the lottery ticket). I have an old neck injury AND arthritis and my neck was hurting so bad after a few hours that I decided to call it quits today. The neck will probably take days to recover. That said, its likely when the car sounds like a grinder when its running that something major attached to the driveshaft has failed - how else would it be possible to punch a hole in the oil pan?

If he hits the 'other' lottery I think MVS is entitled to a 10% tithe - I'm sure it's in the fine print of the TOS/EULA =) If not a P0455 will haunt you at the J and L hoses.

I'd drop the pan - it is relatively easy and you will be able to determine the overall condition of the engine's bottom end. You can't really make an educated guess at this point as what to do without doing so if you are thinking of getting this car back into service. This is really sucky weather to have to do this in... You have to replace the pan anyways to see the condition of the bottom end, so I'd remove it to inspect before I decide if I want to order a new pan or say screw it and junk the whole vehicle.

You could look into a different engine, but I don't think I would until I find the root cause of the existing failure. It may be that something like a log, a chunk of ice, etc hit it with some force.

Good luck on this, stay warm =)

PS - A creeper with a head pad sometimes does wonders when you're stuck under there.

- My theory is either the main bearing or the rod bearing cap bolts came loose on #1, punching a hole in the internal housing of the oil filter area of the oil pan. Just a theory.

The only hint I recall at oilpump removal difficulty is the reference to hitting the lugs with a split edge chisel in the Volvo procedure

Albany NY probably as some cold weather right now but I'm in Atlanta where its just a little cold - about 50 degrees today. I know Albany weather since I spent 4 years in Troy - RPI class of 81. I have a creeper - its the craning my neck to see what I need to see that causes the pain. I found an engine locally with 120K on it for a good price but I'm not ready to go down that road. IKf it had 75K on it I might. Mine only has 173K on it and has been well cared for. The fact that it seems to have self destructed really pisses me off - no much I can do about it though.

Yeah, whatever that means - I read the procedure. I pried it out with a crow bar and several well placed curse words. There's no room on or around those lugs to do anything with a chisel except rotate the oil pump back and forth about 20 degrees. The lugs have holes in them and I put a bolt through the holes and used it to improve the prying action with the crow bar.

If the main bearing came loose wouldn't I have a leak? I had no oil leak except a little bit from the oil filter itself right at the seal.
