How To Replace Intake Manifold Gasket
Posted 22 January 2012 - 02:23 AM
I've been kicking around here for a while trying to find information on how to replace the intake manifold gasket for my corolla. I purchased the car back in July, but in the winter months I have discovered the crazy rev hunting issue on very cold starts (overnight, 30F > ). The car has 53,XXX miles, so it is still pretty young. I have read many places that the Intake Manifold Gasket is often to blame for this cold start problem. Regardless of whether it is or not, I can be almost certain that the gasket has not been replaced before. That whole area probably needs a good cleaning as well. I already purchased a replacement gasket from the dealer, but that is as far as my project has gone.
So I was wondering if anyone would be so kind as to direct me on how to do this. If there is already a topic discussing this then I have not seen it. But if there is forgive me for missing it.

1st pic shows elusive brake booster vacuum hose on intake manifold, which is hidden once throttle body is installed... Intake manifold gasket was easily replaced on friend's 2005 without draining any coolant or disconnecting throttle body coolant lines, by setting (+cleaning) throttle body aside.

I have a few more concerns before getting started though. What kind of lubrication (if any) should be applied to the gasket or gasket seat before reinstalling the manifold? Also, will throttle body cleaner be best for the manifold? Finally, the gasket I received is SKU 17171-0D020, and is a black gasket. I did see an orange gasket offered by RockAuto noted as 'revised'. However, I decided to go OEM and order from the dealer because of my inexperience. Is that going to be a problem?

Your Toyota dealer is supposed to provide you with the new revised orange gasket # 17171–22060 (current part number) as per TSB EG045-07 (Oct 27 2007). SKU 17171-0D020 (previous part number) is the same problematic gasket that's already on there and leaking. For some reason, they're both listed in Toyota OEM parts... Have your Toyota dealer exchange it for the proper one (17171–22060 $5.62 retail).
