Fuel Injection rebuild kit recommendation
One of my injectors has let loose, leaking all over the intake. it is weeping heavily from where the injector mounts into the head and fuel rail. Any recommendation as to where to buy the rebuild kit - BavAuto, 944 online.com? And should I buy all the gaskets and replace them? I heard some companies sell junk and others are good. Any help would be appreciated, thanks.

Can't comment on the rebuild kits but another option would be to send your injectors to WitchHunter Performance for a rebuild and flow test.
They do good work and are reasonably priced. https://www.witchhunter.com/ |
Thanks for the referral, that seems like a reliable and professional option. I really want to try my hand at changing the o-rings myself and trying the DIY route; it doesn't look very hard.

Rennbay is a good source for a kit and I can recommend them personally as I’ve used them several times. Otherwise all the usual vendors should carry something similar. mj951 has a good point though, witchhunter cleans and balances all the injectors and provides all those seals as part of the service. Definitely think about it as it’s a good service and worthwhile wyit job, also it’s not something you can really do by yourself. |
OK, I've looked into Witch Hunter and I think that is the way to go, can't beat that service for the money. Peace of mind, too.

You could probably bench test the flow visually using injector cleaner, you'll probably want to flush with fuel. Or else, in the car by jumping the fuel pump to stay on and opening each injector one by one spraying into a cut open bottle or cup. You won't know your flow numbers but you should be able see if the spray pattern looks consistent or not. The orings arent anything special, most hardware / autoparts store probably have ones that will work. Just take one in that's have decent still and match it up. That being said a new or refurbished set of injectors make the car run real smooth. Probably worth the investment.
Fire extinguisher near by just in case lol. |
Has anyone tried the deluxe kit that 944online sells, with fuel injector elements/tool?

I used the Rennbay fuel injector seal kit and have had no issues after 6 months of daily driving.

You can get the o-ring kits at any local parts store. They are not 944 specific.

Replacing the external o-rings is easy, few different vendors with kits with all the necessary parts. Witch Hunter removes the internal screen, and cleans out all the varnish etc.. inside the injector then verifies the flow. This is not a DIY job unless you have the proper equipment.

Trying to "eyeball" the correct o-ring using a 20 year old shriveled up one as a reference....versus buying a kit with the known perfect parts, just order the kit. |
