Ok guys I need some help , I bought a 1981 242 at the auction and I am trying to change the flame trap . Everyone acts like this is an easy job I cannot get my hands to replace the new one . Is there a trick to this or am I just plain stupid . I have an 89 760 Turbo I do all my work on it ok . Also is the 242 a very good car I bought this car at the auction for hardly nothing and it runs so good . Are there any quarks about this car I should know ,,,,

there are two hoses that connect to the top half of the flame trap, one small and one large. Follow the large hose from the fuel/air control housing and once you feel the top half give it a yank and it should come right out. You'll have to dislocate you thumb to get your hand between the intake support and the air boot (just kidding but only a little). It should get easier with each successive attempt.

You got a great car (I have the same). Is it a manual?

Good Luck. Adam.

Well, if it doesn't look realistic to find a way in there, just yank the intake manifold and you can do some other needed service at the same time.

- clean and replace seals on injectors
- clean throttle body
- clean out the gunk on, below and around the air flap
- clean out the carbon build up in the intake manifold.
- clean the plastic housing (breather box) that is attached between the flametrap and block, it could be clogged with gunk
- check condtion of wiring harness


Just remember to label and draw little diagrams of the intake hoses and connectors before removing manifold. Getting nut number 6 off of the manifold is a little difficult, I found that if you pull injector number 4 first, it makes it easier.

Snatch a small child off the street and have them wiggle their hand in there or buy the curved needle-nose pliers tool from ipd. I'd recommend a slightly built 10 year old boy as having the proper strenght and hand size to do the job.

I managed to get by with a 13 year old son. But it was a tight fit. And then there is all the crying and pleading: "Please Dad - Not Flame Traps Again!!!!"

Just kidding. Buy the ipd relocation kit so you only have to place something under that intake manafold once every 10 years.

Happy Rolling.

I've had 245s and 244s, never a 242. If the 242 has the same engine/transmission (I think it does) then your 242 will outlast your 760T. These cars are built like tanks. But it will never handle like your 760.

The flame trap sits below the intake manifold. The flame trap is inside a black silicone rubber tube-like thing that has a 45 degree bend in it. Sounds peculiar, right? Shine a worklight under the intake manifold behind the throttle body and look: the only thing resembling that description will be the flame trap.

The rubber flame trap body has an upper and a lower half. To change the flame trap, you or an assistant (got any kids?) reach behind the throttle body toward the engine block, grab the upper half of the rubber flame trap body, and pull up. You should be able to pull the upper half off and the flame trap will be inside. Clean it until oil vapors can easily flow through the little holes.
Then put everything back the way you found it. Hard to describe, perhaps hard to see, but not so hard to do.

Especially if you get the flame trap extension from IPD. This nifty gadget extends the rubber hose so you can relocate the flame trap someplace where it is more readily accessible. Great gadget!
