Oil Filter Burst......Do I need to look deeper?

[SkiDoc]

2006 DCB 29 with twin 200hr. Ilmor 625’s.
A couple weeks ago I was cruising about 3000 rpm and I thought I smelled oil. About the same time my wife said the same thing so I shut the boat down. Oil pressure was normal . I raised the hatch to see oil spewing out near the oil filter area. Luckily we smelled it and shut down before oil pressure was lost.
The affected engine was the starboard and it is really hard to see the area. We idled back to the ramp on the port engine. Before we put the boat on the trailer I put my head down there and had my wife briefly start the engine. I was almost sure that the spray was coming from the cloth braided hose that carries oil from the block to the oil cooler. So I replaced that hose. Cranked it up and didn’t leak until raise rpm to 2000. This time could tell for sure that the oil filter was split. I replace it and ran it again and it all seems okay with a very easy run. The filter was the Mobil 1 204a extended protection.
I have never had anything like this happen. Should I look into something that could have elevated the pressure within the filter which would result in the split?

I'm not very familiar with the 625 Ilmors but I would probably want to check out the oil pressure bypass in the block if this were to happen on any other engine

See if there is a lot number on the filter and give Mobil a call and see if there was TSB or recall on it. Sometimes these manufacturers do silent recalls.

I seem to recall this happening years ago to OD1 on an Ilmor

Remote filters right? what was the high Oil pressure reading at the time (while running above idle ?

That’s not the first Mobil 1 filter to do this. It happened on one of my vehicles. I read from the guy who did that study years ago that he had heard reports of their filters leaking. They have the best media but there is an issue that will (rarely) cause the filter to develop a leak at the base where the seam is.

I think you can still read about it here.

Found the quote:
Though I have never had problems, I had received feedback from a few people back in 1999/2000 that these filters may leak at the base. It seems that the seal between the backplate and can may burst under high pressure (at startup). These were on Ford engine applications.

Check bypass. Had this problem with a motor here and kept blowing the Wix filter.

When I worked at a dealership we had a 4.6 t-bird come in on the hook with a burst oil filter. Weird screwed a filter on it filled it with oil and started it up. Oil pressure guage went full tilt and it burst the filter again the pressure bypass in the pump was stuck . It was under warranty and Ford put a new motor in it.

Very common problem on those ilmors. Doesn’t seem to matter what brand filter. Have seen it smoke bearings if you lose pressure.

This. Very common. Mopar came out with thicker filter to fix this issue 15 or so years ago.

I think it is still the same part number but AB at the end now.

I have used a lot of K&N filters on the engines I built, due to their specs. Might want to look them up to make sure they have not changed, but they have a thick case, supposedly will withstand 300 psi if my memory is good. I will say I have not been around any Ilmore stuff.

This is not the first time I’ve heard of this happening on a viper motor. You are sure it split the filter housing and not just leaking around the o ring gasket?

They split, very common. Took out my buddies engine in his F29 two years ago. Was common in the cars as well. Use the filter above. It was made to fix this issue.

 

[SkiDoc]

Here is the filter. Wow thanks for the responses!!! The oil pressure gauge mirrors the other side at 75lbs, never did drop. Would the pressure gauge show increased pressure at the filter?

 

[Mikes56]

Did you recently have the oil changed to a thicker viscosity? Was the oil still cold which made it thicker and created more oil pressure than usual?

 

[SkiDoc]

Not any different oil. I have used Mobil 1 15w-50 as manual recommends. It split on a very hot day. I had run moderately hard then had lunch and was just cruising back to the marina. I do think I had tightened filter with the wrench more in the middle vs the end.

My filter is on the block and not remote

Just a bad filter probably....can got drawn too thin.

Fram HP filters have a can you park your truck on without crushing it....I'd probably switch to those or some other HP/Race filter with a thicker can. Absolutely no point in running an "extended life" oil filter on a boat where you change the oil the equivilant of every 500 miles in a car.

Throw a whatever filter on there and fire it up....if oil pressure is where it should be, it was just a bad filter....if it pins the gauge you've got bigger problems.

Don't tighten it with a wrench, tighten it as tight as you can with one hand. You are actually supposed to tighten it 1 turn past the o-ring touching the block but sometimes you end up with a drip, shops tighten them like I described above.

Have a friend with a 28 Daytona over there with twin 625’s in it, he’s split 2 oil filters so far this summer. He brought it to I believe Barrett? but not positive and they fixed it. It had something to do with a bypass rod or something like that in the block. Quick fix for him once they diagnosed it.

Anyway you can get me in touch with him? Thanks

His name is Tim, his cell is 360-797-4470. I told him you’d be calling so he’s in the loop.

Assuming you’re talking about Tim?

Edit- yep.

Agree. Fram redesigned the HP series in 16 or 17. They are very high quality.

This is the first thing I would do and I definitely would not tighten past one full turn.

I like the Wix Racing filters. Ive personally seen em hold up to over 125 psi with no issues.

Always tighten a filter by hand. Never use a wrench to do this.

I have an Ilmor. The expert in Havasu is AJ at Barrett. Good luck … probably all good.
