if I "fly below the radar" on this one may I suggest a dipstick test ? why? dunno ,its my default setting for all questions oil related (dons nuclear blast suit ,gathers month"s worth of rations and makes way to cellar )
Loads of recent threads on this. Zed reckons his barely reaches 60 deg unless he's screwing it, someone else last week reckoned 130! Worth remembering that in this warm weather the oil will be considerably warmer than in the colder months.
Our air-cooled Kawasaki bikes run at 125 degrees C to 150 degrees C. So I was taking that as a pointer.
oil needs to reach at least 100 to remove the moisture content , 90 to 110 is the range i get in my type 4 with the porsche style taco sump sender
Ditto the dipstick test. If it's too hot to hold, your engine's getting too hot. I found this out just after I got my van.
I reckon my gauge (or sender) is naff. I saw 140 all weekend but with no loss of power or running issues? I think I have a calibrated NIR laser one somewhere, I'll point that at the sump and compare readings, then hopefully I can stop panicking.
I'm presuming then, you've got a temp gauge with a probe stuffed somewhere? It's common knowledge these are unreliable. Had this conversation many times on the JK site over the years and the conclusion was VW didn't put oil temp gauges in for a reason.
Bus came with a sump plate sender unit fitted and a gauge but the gauge had never been fitted. I was fully laden cruising at 60 up the M5 with no issues, saw 140 degrees, this dropped to 120 when on ordinary roads. Again no issues but I don't want to kill the bloody thing now I've just got it running! I think I'll put my own marks on the gauge based on the industrial calibrated sensor and leave it at that.
Makes sense. The faster you go the hotter it gets. Laurie Petit once told us at tekenders, the biggest reason for engine failure was hammering it.
Agree with that! Whilst my Bay can do 80mph (you have to try once just so you know) I rarely, if ever, go over 60mph as I find this much more comfortable, 55mph is the norm.
I found that out when VWOlive blew her engine up. I've never felt a dipstick that hot. I'm not sure on the bus what he runs at because I don't have a worry gauge but the ragtop oil goes from 96-114 depending on how hard I'm driving down the freeway.
Busses, by the very nature of their lack of aerodynamics and gearing, are going to run reasonably hot... Ideally you want to keep the oil under 130, but the gauge would need to be calibrated to corroborate the temp you're seeing!!
Mine seems to top out at 125, if really cane it, but that's just cruel. 80-100 around town, 115-120 cruising. The 1600s weren't designed to cruise at 70 or more: they just get hot.
I've just done a long motorway run this weekend. Mine didn't go above 95C and was mainly at 90c. That was at a pretty steady 70mph at approx 4k rpm and Friday was one of the hottest days so far this year. My Oil temp is measured by an uncalibrated dip stick sender and vdo gauge. My previous engine used to run hotter, 120c?, at lower speeds.
That's interesting. I try not to go over 110 C as I vaguely remember reading that was sort of a limit. Snotty and lhu1281 always sound like they know their stuff so I will probably not change how I drive but not be so botered if the temp creeps a bit above 110 C in future. I understood that overheating knackers heads on type 4s but the bottom ends are fairly bomb proof so I didn't want to risk it. I have a Porsche Taco plate mounted gauge and whilst I do get the VW didnt fit one thing Porsche did to the same engine in that specific place so its better than nothing I guess
If your engine's in good shape, don't worry about it. Aircoolers bang all over the place, but seem to survive.
I have the sender in the type 3 dipstick blanking plate (AS41 case). I was told this was the best place for it to be. ours never seems to get above 100 degrees on the gauge. normally runs at about 90 degrees C
Will the temperature vary between type 1 1600 and type 4 engines and if so how much roughly, I guess a type 1 will run at a hotter temp?
