Wrap the headers?
Anyone with headers having Oil Temp issues?
Just like it says- Oil temperature is skyrocketing (got up to 300 while cruising 45mph), and I can't think of anything other than heat from the longtubes (they're right next to the oil filter). Yes, I've had the IPC update done per the bulletin. Oil level and pressure are fine.
Any thoughts, header people (or anyone else with a suggestion)?

Was at 255's to 280's but will let you know when I fire up the 427 in a week
to seeif there's any more increase. Oil cooler, diff cooler and a trans cooler are all my note to Santa...I even gutted my trunk to make room:thumbsup:

I'm sure that if it is the headers I can solve it through any of the aforementioned methods, but why can I not remember a single person here having this issue? If I'm the only one, then the headers are likely not the root cause.
Anyone else with Kooks experienced this, or do I need to look elsewhere?

Tony I am in swfl and I hit those temps without headers somedays. I was concerned myself.
There's no question that it's bad for oil to get this hot, as it loses its ability to lubricate.Tony I am in swfl and I hit those temps without headers somedays. I was concerned myself.
Tomorrow we'll be checking to see if the damn lovebugs have gunked up the front coolers, but other than that I'm drawing a blank. There's no reason it should get that hot.
I agree. what weight oil do you use?
5W-30 Mobil one (OE spec)
Don't really watch my oil temp much. Will now.
I have Katech "off road use only" headers. So obviously I only drive "off road."
Keeping that in mine......in Scottsdale where it's really hot now, my oil temp runs around 218 - 222.

Like you say Tony, I don't remember anyone else with kooks mentioning this problem. Mine go on this week so I'll be interested to hear what you find. I rarely cross 210 in normal driving now.
Mine has always hovered around 240-250, even before the headers. It's been the same since the header install, but yesterday it just shot up on the way home from the golf course. I noticed it around 280, and then the warning light came on at 300.
This morning was the first time I drove it since Sunday, and it was up to 190 by the time I got to work- It normally only has time to get to 120-130, so I know something's up.
It really baffles me, since if the headers were to blame it would have done it immediately after the install.

Well, I see your first problem...you golf...Mine has always hovered around 240-250, even before the headers. It's been the same since the header install, but yesterday it just shot up on the way home from the golf course. I noticed it around 280, and then the warning light came on at 300.

Start with the simple things:
1. Is the oil level full on the dipstick - 6.5 quarts?
2. Are the sensor wires damaged, melted or pinched from the header install?
3. Test the signal circuit for a short to ground.
4. Check the sensor connector itself for a hokey connection.
5. Chuck the oil temp sender in the trash and install a new one.
6. Chuck the IPC in the trash; replace w/ new.
7. Be thankful you work at the dealership and don't have to fight the same battles as the rest of us. :thumbsup:
Your oil temp should within run 10-20 degrees of the coolant temp which puts it in the 215 to 225 range. Extended high rpm will run it up quick - drive like my wife and never go over 2200 rpm. :highfive:

Mobil-1 has a good "Viscosity Index" (169) which measures the performance of an oil under temperatures (test temperature is 212 F) and pressure. It's flash point is 446 F so it will hold up to the heat issue. I've just spreadsheeted all the synthetic oils for performance under standardized testing and Mobil-1 is there with the good ones. Sorry doesn't help with the problem, but hopefully offers a little peace of mind.

The hottest mine has seen in "normal" driving during the dog days of late july-aug summer here in Texas is 230. On those days outside temps were 100-110 deg.Mine has always hovered around 240-250, even before the headers.
Hey Tony, 89 degress here today in North Bama and my top temp was 219 briefly but averaged about 210-214.
Okay, problem solved.
Whoever attempted to reprogram the IPC per the bulletin for incorrect oil temp display didn't do it right, therefore it was still reading incorrectly (even though it had supposedly been done). GM has recently released a supplement to the earlier bulletin that instructs the tech to slow down the baud rate on the IPC before relearning, or the process won't complete.
So as it turns out, the oil never got that hot. Sorry to cause any worry among header owners- false alarm.

Thats kind of what I was thinking. I was going to suggest that the first thing you could have done to quell your worries was just put a mechanical temp sensor in and verified what the IPC was saying.
Glad you got it figured it out.
