Before I get any crap, I just recently read that for some reason Fram oil filters are looked down upon. Please educate me as to why but also keep in mind that I expected to use this filter for about 10-15 hours at most. Now to the real reason for the post. What is this? And why is it leaking and do I just replace it to stop the leaking? For reference this is directly below my oil fill port on my GT40 Pro Boss EFI, and next to my oil filter.    Thanks Brian ------------- 2005 Ski Nautique |

Hi Brian, First, I'm not really sure why others seem to look down of the filters though I'm sure you'll soon find out. I don't personally use them because my experience is the filtration isn't very good, certainly not as good as a Motorcraft which is usually readily available and only a few $ more. What you are looking at is an extension "T" off of the engine block for the oil pressure https://www.skidim.com/prodinfo.asp?number=R020001" rel="nofollow - SENDER and the oil pressure https://www.skidim.com/prodinfo.asp?number=R020015A" rel="nofollow - SWITCH . Your https://www.skidim.com/prodinfo.asp?number=OP22900" rel="nofollow - Switch is a bit different and seems to be found on a lot of GT40's - don't know if they had just been replaced by the wrong part at some point or if PCM decided to use a different one somewhere along the way. But mine came with one like yours - and was leaking also and I had replaced it with a like kind before I knew the GT40 specific one was different. I'm sure someone will chime in on this to clear it up. Leakage from the units themselves requires replacement. If they are leaking from the fittings or the "T" is leaking at the block you should be able to tighten them to stop or reduce it. The larger of the two is the sender for the oil pressure gauge and the smaller is the switch that will initiate a SLOW or LIMP mode via the ECM (computer) if the pressure drops below a certain level. ------------- JCCI 1995 Ski Nautique GT40 |

You mention that your filter will only be used for a short time. For that purpose the inexpensive filters are known to outperform the quality filters. Engine rebuilders have known this for years. Use a cheap filter for breakin then switch to a quality filter for normal use. A Hastings filter rep explained why this works. The cheap filters catch a lot of debris at first and then the bypass opens exposing the engine to unfiltered oil. The high quality filters don't catch quite as much at first but perform much better in the long run. He had a display showing the internals of many brands of filters which we discussed while looking at them. Hastings makes a very high quality long term filter by the way. I also like the premium Wix filters. Motor raft and AC Delco or Mopar do not make filters, before trusting them you need to know who actually makes them and what quality they are buying as each manufacturer makes a few quality levels and can provide good or cheap filters by request. If you want to know if a filter is good or bad you need to cut it open and look at the filter and the bypass valve. In my boat there is no such thing as a long run, I only run 25 hours a year. In a car that would be less than 1,500 miles? If I change my oil every year how would I benefit from the quality filter. ------------- |

The 5th and 6th items down in the link are the switches Joe mentions.and the wording says the older smaller style was replaced by the newer big one. so there's the answer  The smaller one from SkiDim also says it's for Indmar engines. I figure it would fit, but who knows what the setpoint is. https://www.skidim.com/products.asp?dept=1041" rel="nofollow - link |

According to their site it is a 6 psi switch. GT40 service manual indicates SLOW mode should initiate at 5 psi so technically the switch should work since I believe they are both 1/8" NPT but the SLOW mode may engage 1 psi sooner, which isn't really a bad thing since 6psi is really too low anyway, IMO. Having said that, if I had known there was a newer version that I was supposed to use I most likely would have gotten it instead. ------------- JCCI 1995 Ski Nautique GT40 |

Here's another oil filter link from CCF a few years back How'd that orange filter on Brian's boat do in this person's test/evaluation of filters Hint.... pretty goodSome people can look at things objectively, some can't http://correctcraftfan.com/forum/forum_posts.asp?TID=29603&PN=1&title=oil-filter-comparison-evaluation" rel="nofollow - link I can't even find my favorite filter in any of these filter tests |

You should have taken the oil filter off first, then you would not have gotten so much crap. ------------- ------- They are only original once! ------ |

So I switched out the sender with this part and ran it today and the oil pressure gauge read I thought high. Is around 70 normal? Oil Pressure Sender Sensor... https://www.amazon.com/dp/B0797CHW8J?ref=yo_pop_ma_swf ------------- 2005 Ski Nautique |

Brian, That 70 PSI sound high. Was it that high before you replaced the sender https://www.amazon.com/dp/B0797CHW8J?ref=yo_pop_ma_swf%20" rel="nofollow - with this one from Amazon? The way to really get a good idea of true oil pressure is to T in a mechanical gauge next to the sender. Did you get the one from Amazon because it was less expensive? ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Marine oil pressure gauges have been pretty standardized with a range of 0-80 psi for a long time now. If your gauge is a 0-80 and the new sending unit is also a 0-80 they should work together. If it was cold oil right after startup 70 wouldn't be a big surprise Warm oil high speed it wouldn't be a surprise either with it dropping down when you come back to idle. 70 all the time would be a surprise though meaning "something ain't right"

Thanks Pete. Yes, I was trying to find the same part for less. ------------- 2005 Ski Nautique |

Thanks Keno. Yeah, it stayed 70 when cold, warm and rev’d up. I think I’ll put the old one back in and see what it says. I don’t remember it always reading that high so I’ll check again. ------------- 2005 Ski Nautique |

The part does cross-reference to the PCM replacement R020001. Sometimes, you get what you pay for - generic or 'overseas' parts aren't always the best deal If the sender checks out OK the list of 'easy' fixes is fairly short: gauge or wiring. ------------- JCCI 1995 Ski Nautique GT40 |

I swapped the old one back in and sure enough it fluctuated and stay around 40 when idling. Do you think it did that because it was bad or not the right type? ------------- 2005 Ski Nautique |

I guess this would lead to the question of "what's wrong with the old one?" A dual station sending unit like Outerbanked mentioned will read twice as high as as a single station sending unit when used with a single gauge. That's probably not your problem since the gauge goes to 70 and doesn't move with the new sender. Like gt40KS said the part number cross references to the original PCM number. What does the gauge read when you turn the key to RUN with the engine OFF? Here are some troubleshooting instructions in the link. Don't mind that they say Teleflex, they apply to your Sierra also https://www.jamestowndistributors.com/userportal/document.do?docId=835" rel="nofollow - link |

It seemed to be working properly but it was leaking a little oil. ------------- 2005 Ski Nautique |

Did you clean up the area to get a good look at the source of the leak? Maybe it was just the threads? If it is just the threads, don't use any pipe sealant or tape. The body of the sender is the ground source via the block for the gauge circuit. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |
