Default Verona Rear Main Seal

Hello all,

I towed my 2004 Verona in to the dealership when I realized my rear main seal was leaking heavily. They said no problem to fix. When I picked it up in a couple of days, I got it home and it was still leaking heavily. I took it back and now they call and say my flex plate caused too much damage to the engine block and area around the seal and they can't get it to seal now. BTW, my engine would crank and run fine so the flex plate was apparently not totally broken.
I had a mechanic friend who said that didn't make sense. I also have been trying to find out if the verona has a replaceable rear main seal housing. I saw one on Ebay for the 2004 Verona, but can't find a picture of the area around a Verona engine or a parts breakdown. The oil leaks from behind the starter motor. I degreased this area and cranked for a bit and then removed the starter and that's where it is coming from.

Do you guys have any thoughts on this? Are they right at the dealership that the block could be so messed up that it can no longer get a seal? Couldn't they replace the rear seal housing (if there is one)? Is there some other source of the leak?

I am supposed to go down to the dealership next week and meet with them.

Thanks for your help!

Brian

I don't know if there IS a replaceable seal housing, but even with that said, it is possible to incur block (or crank) damage to the extent that rear main sealing is unobtainable.

Without pictures and a damage findings report, we can't better asses the issue with you.

Max,

Thanks for the reply. The shop foreman said he didn't take any pictures, but for an additional amount, he can open it up for me to see (additional $150.00). If it is unrepairable, I don't want to spend another $150.
I can't seem to find any photos on the web showing the rear main seal specifically for the 2004 Verona. If I found one, I could be better prepared for the discussion.
I don't understand yet how a cracked flex plate could cause damage to the seal, since the seal is inset into the block. I am not a mechanic, so I am just trying to understand. My friend who is a mechanic (well versed on engines) showed me why he was wondering the same thing.

Well, hopefully I can get some photos of the seal before I write off my car. They are also on one hand, trying to sell me a new car, which is why I am a bit suspicious.

Thanks for your help!

Brian

I am attaching a couple of photos I took when trying to find where the oil was leaking. As you can see, the flex plate is in its place and cranking the engine was no issue.
My Verona has 186k miles and I bought it used at 120k miles. Yes, it appears that the engine is a replacement.

Appreciate any comments.

Thanks,

Brian

I guess if the flex plate grenades or jams the engine block with bent (right angle) spinning plate edges, then all hell would break loose on the block / seal area.

Not a super view, but I see no parts in this exploded view that could be construed as a rear main seal (separate) housing.

Yes, I see your point. I have included a photo taken from Ebay and a link to the Ebay page and explanation that the part (rear main housing) was removed from a 2004 verona. If it really had one of these I would assume it could be replaced and get a good seal.

Thanks for the diagram. I wish I had an end view (photo) of the rear main for the Verona.

Thanks,

Brian

I better understand your dilemma now.

Thinking about this further...engine blocks have "cast in" sections for oil galleries with plugs (to route oil to the upper portions of the engine / head) that PROTRUDE out of the back somewhat. I wonder if one got deeply nicked by the broken flex-plate?

That's a good thought. It may be something like this where they put a new seal in and maybe didn't check to see if there was another source for the leak.

You should be able to crank the engine with the transmission pulled away to see the source of the leak, right? Even if a new seal didn't make the best seal, do you think it would leak that much?

I know that the oil leaks when it is running, so whenever I stopped I still had about an 8-9 inch diameter puddle under my car after the new seal was put in. The day after them putting in the seal and replacing the oil and filter, I checked my oil level and it was at the minimum line. I hadn't driven but about 20 miles.

That's a good question.

I've cranked transmission-less STANDARD tranny set-ups (with full flywheel / ring gear) but never a Automatic / flex plate unit, sans torque convertor bolted up. A cranking strength issue? Not sure.

What MIGHT safely work is to introduce (max 40 PSI) shop air at the sender switch port (pressurizing the oil gallery circuit) and look for air leaks in the area of concern. Not an ideal pressure substance (not viscous) but possibly a vehicle to spot a glaring leak issue. That and I think that trapped oil will immediately exit the leak spot before the air will.
