Sorry, I have a 76 tiger O-360-a4k. Although in the last post I did say that the temps went up after a fuel stop. I originally saw the problem on a longer trip with no stops. I guess I just need to see what a tiger in good shape looks like under the cowling. Is there a site out there that has good pics of the baffle and baffle seals? Also is there anywhere to but a baffle kit? The temps were around 86F outside. I have had the airplane for 2 months and have flown about 12 hours ... the problem seems to have come up in the last few hours. in those 12 hours i have burned 1.5 quarts of oil. So this may be a contributer that has uncovered the problem. It now has 6.25 quarts. I have had a few different CFI's in the plane as well as a grumman pfp cfi. And none of them noticed the higher temps so I dont think that i just didnt notice it earlier on(although the days were a bit cooler then). Thanks Much for inputs Thomas 74225 D73 ________________________________ Message 2 _____________________________________ Time: 07:24:31 AM PST US From: "flyv35b" Subject: Re: TeamGrumman-List: RE:High Oil Temps --> TeamGrumman-List message posted by: "flyv35b" My comment would be to first check your oil temperature gauge per the maintenance manual. You should buy one if you don't already have one. If the gauge is accurate then there is something amiss as Tigers typically don't run over 200 F, even with 90 F ambient temps. Also, 8 hr/qt is not all that high oil consumption and not abnormal. Have you checked your engine compression lately? Your baffling could be a significant contributor but not to a recent sudden jump up in oil temperature. You could have a defective vernatherm valve that is bypassing oil around the cooler or possible excessive piston ring blow by gasses that are heating up the oil. Gary Vogt has some photos of baffling on his web site I believe (www.AuCountry.com).

OK, some questions. 1. Are your cooling exit ramps deteriorated and sagging? 2. What do your baffles look like? Look inside your air inlet and look to see how the baffle seal seals around the edges. 3. How old are your oil cooler hoses? Were they professionaly made? Do they have date tags on them? 4. Do you have a spin-on oil filter. If so, is it a recent install? or has it been on a while? It is possible the Vernitherm is not sealing/opening correctly. You should see an even imprint on the mating surface. ________________________________ Message 4 _____________________________________ Time: 10:28:22 PM PST US From: TeamGrumman@aol.com Subject: Re: TeamGrumman-List: High Oil Temps 74225 is a 76 Tiger.
