I.Mupferit Posted September 6, 2005 Author Share Posted September 6, 2005 It's only really a Raceline issue I think as their wet sump and oil filter plate are designed to use the old crossflow filter Tim, so no need to worry. 😬 The problem has only arisen because I hadn't realised the difference between 2 apparently similar filters for similar vehicles. When I bought the filter, Halfords didn't have the HOF203 for the MK 2 Escort Mexico but they did have the HOF200 which, according to their booklet, suited the MK 2 RS1600i. Now I thought to myself, well that basically was only a X/Flow block with a Cosworth top end on it so I can't see why it shouldn't be ok and externally it looked identical as well.

Rob Walker Posted September 6, 2005 Share Posted September 6, 2005 Brent I don`t want worry you but are you sure the Champion filter does not have the valve ? Some of the valves are not visible from just looking down the hole as some have a flat plate with the spring behind the plate, I have cut several open to discover this. IIRC the filter that I fitted on Tom Hoods 2.3 was a Fram off an Escort Mexico 1974. This is also applicable to all K series owners the filters with this valve are to be avoided.

Rob Walker Posted September 6, 2005 Share Posted September 6, 2005 Escort Mexico mk 2 had a 1600 pinto engine the RS 1600 was a BDA based on the cross flow block. The Escort Mexico Mk 1 had a 1600 cross flow. Edited by - Rob Walker on 6 Sep 2005 08:33:08 Link to comment Share on other sites More sharing options...
I.Mupferit Posted September 6, 2005 Author Share Posted September 6, 2005 Sorry, yes I meant the Escort Mexico MK 1 and no, the Champion C103 doesn't have the valve. And you are right again I should have left the 'i' off the RS1600. It's all these numbers and letters, they get very confusing for an old man.

MikeE Posted September 6, 2005 Share Posted September 6, 2005 I was a bit stressed there until I got down to the recommendation for the HOF203 which is the filter I use R400 Duratec Build and Modification Pictures here Link to comment Share on other sites More sharing options...
Mr Locust Posted September 6, 2005 Share Posted September 6, 2005 This has obviously demonstrated that the much maligned Caterham oil gauge is capable of reacting quickly enough to show potential problems when functioning correctly?

I.Mupferit Posted September 6, 2005 Author Share Posted September 6, 2005 I really don't think the gauge is too bad when, as you say, it is operating correctly. Mine is not very heavily damped and does appear to react pretty quickly so I hesitate to malign it at all. Even in my old seven which I owned for seven years, I never had any problems with the oil gauge or sender. The temperature gauge sender, however, is a totally different story ☹️ Brent 2.3 DURATEC SV Reassuringly Expensive R 417.39 😬 Link to comment Share on other sites More sharing options...
moosetestbestanden Posted September 6, 2005 Share Posted September 6, 2005 Hi Brent, My update is no update at all. I screwed up my lower back yesterday and couldn't even sit down in car. Getting old is a bitch. A trip to the pharmacy today should loosen things up to the point where I am mobile so I'll conduct a test this afternoon (Left Coast Daylight Time), come hell or, ahem, high water. Btw, the engine was built w/ the Raceline oil filter housing. Do you have the same? ------- Chris Vitural distance is only as far as you think it is Link to comment Share on other sites More sharing options...
I.Mupferit Posted September 6, 2005 Author Share Posted September 6, 2005 Yes Chris, I do have the Raceline oil filter housing. Did you see my post about the sump capacity and Metric/U.S. volumetric conversions 🤔 Hope your back gets better soon, you have my sympathies being a sufferer of long standing myself.

ELV15 Posted September 7, 2005 Share Posted September 7, 2005 I've been using a fram filter from day one...I'll check to see if it has this relief valve...I suspect it does. ☹️ What's the easiest way to open a used oil filter?

DaveMorris Posted September 7, 2005 Share Posted September 7, 2005 It appears that the same thing has been happening on my crossflow 🙆🏻 Symptoms have been drop off in oil pressure at higher revs, most notably when the engine and oil were fully up to temp. Actions taken so far have included - Changing oil and filter (which I now know is the valved type) Changing dry sump pump Swapping over to mechanical oil gauge. And the worst of it all is that I have a spare 203 filter in the garage I'll try just swapping filters over to see if that is the cure. Link to comment Share on other sites More sharing options...
RiF Posted September 7, 2005 Share Posted September 7, 2005 Don't knock all Fram filters as I have only been using Fram and have not had any problems (yet ) I expect it is the X flow version though, number PH966B. At a price under £3 doubt if it has a valve?

I.Mupferit Posted September 7, 2005 Author Share Posted September 7, 2005 Hopefully your problem is the same Dave and will be as easy to solve when you change the filter. Brent 2.3 DURATEC SV Reassuringly Expensive R 417.39 😬 Link to comment Share on other sites More sharing options...
I.Mupferit Posted September 7, 2005 Author Share Posted September 7, 2005 BTW Richard, my other problem as we discussed recently does appear to be improving with more miles on the car. I have now decided to leave it until next spring to see if it goes away completely. I will keep you informed.

stevefoster Posted September 7, 2005 Share Posted September 7, 2005 Good about the oil filter issue, Brent. My XF used to run these sorts of pressures but I always used the good old XF filter and hence I guess I never had any problems...

dannylt Posted September 8, 2005 Share Posted September 8, 2005 I have strange oil pressure also, bu tin a different way. By the time the oil is warm (65+) the pressure is a steady 75 up to about 5000. But above this RPM it blips up to 85, and even 90 on occasion. I was wondering if it was a stuck relief valve - are these straightforward to simply replace on the Duratec - where is it? I'm also wondering know if it might be a voltage issue, or from this thread, the filter! The car as built had a very short Fram on the RaceLine adapter to not foul the cross rail. I've since replaced with variously HOF266 and the equivalent Champion - could it be these filters have restrictive flow and increase the pressure? Both appear to have a relief valve inside. The car is a dry sumped 2.3. Link to comment Share on other sites More sharing options...

dannylt Posted September 8, 2005 Share Posted September 8, 2005 HOF266 is same as HOF203, but it much shorter so it fits without interfering with a chassis rail. Link to comment Share on other sites More sharing options...
ELV15 Posted September 11, 2005 Share Posted September 11, 2005 I did some more research today and found out some more info: 1. the stock duratec filter has a oil pressure relief valve in it with an 8-11 PSI opening pressure. 2. the filter I have been using, Fram PH3614, has an oil pressure relief valve with the same operating range. 3. I found a replacement filter, WIX 51034, does not have this valve. It does have the same flow rate and is 4.5" in height. I'm changing my oil tonight and will try out the WIX filter and see how it affects my oil pressure. Why does Raceline recommend not using filters with this oil pressure relief valve? The stock filter has it...? 🤔 BTW Richard, the Fram filter you are using also has a relief valve.

ELV15 Posted September 12, 2005 Share Posted September 12, 2005 Oil is now changed along with a new filter that does not have the pressure relief valve in it (see the Wix number in the previous post for the exact part number). The oil pressure is certianly higher while warming up and at idle. It seems to be around 4 bar when running at RPM's. 😬 😬 😬 Cheers, ELV15 - Tom in California - 200hp duratec powered 2003 Clubsport Build pics here: here Link to comment Share on other sites More sharing options...
ELV15 Posted September 13, 2005 Share Posted September 13, 2005 Update. 800 miles on the new filter. Oil pressure is around 6 bar when cold. Drops to 5 bar when warm. Idles at 2 bar (1000rpm). Using 20w50. ELV15 - Tom in California - 200hp duratec powered 2003 Clubsport Build pics here: here Link to comment Share on other sites More sharing options...
moosetestbestanden Posted September 14, 2005 Share Posted September 14, 2005 Don't knock all Fram filters as I have only been using Fram and have not had any problems. I expect it is the X flow version though, number PH966B That's the number of the filter I've been using. My update: it seems that, umm, ahem, adding the correct amount of oil as per the manufacturer's reccomendation (not the dealer's, ahem again) has cured my ills, w/ the PH966B in place. There's this certain sequence of corners hereabouts where any oil pickup issues are quickly revealed. Several runs through showed no problems. Several more runs through were made just to be sure. 😬 The back is better too ------- Chris Vitural distance is only as far as you think it is Link to comment Share on other sites More sharing options...
I.Mupferit Posted September 14, 2005 Author Share Posted September 14, 2005 Chris, do you think maybe you should do just one more run to be absolutely certain 🤔 😬 Glad the back is better too.
