Frankenstein: The Good, The Bad and The Ugly

That is true for the upstream sensors which I have, but not true for the downstream sensors which I do not have connected, nor have been since 2010.

We'll, maybe that is why you are having an issue with the car tuning since that time then.

[DesertDawg]

Ossme,

I have checked and double checked - the downstream sensors only report efficiency of CAT and do not affect mixture.

At least that is what I have been told. In any case FlyinRyan will turn them off when he does my custom tune.

I very much doubt it. The downstream O2 sensors are only there to monitor cat function and won't affect the tune. If you delete the cats, you only have to disable the downstream O2 sensors in the ECU programming to keep the CEL off. If you don't, the CEL will come on but engine performance won't be affected.

The fluid should be pinkish.

Thanks for that DIno

Anyway, just for good measure I added a third transmission cooler before lunch...

I then did an engine on test to ensure all connections were good - but a green fluid dripped on me - not the expect pink (thanks Dino!).

Further investigation revealed that my three month old thre row all metal Serk radiator was leaking.

So that radiator is now out and Franki is closed for business.......again.

Dave please let me ask you from where you got this oil cooler? online or locally? What do you advice for stock 4.0 2001 xj?
Appreciated.

[DesertDawg]

After trying various configurations, my advice is stay with stock: primary cooling via oil cooler embedded in water radiator supplemented by stock cooler in front of radiator.

I have added a temp gauge and this shows stock is perfectly adequate.

Jeep knew what they were doing.

So is Frank N. Stein open for business again?

[DesertDawg]

I have just had the radiator repaired for the fourth time. Hope to test it later on a trip.

How was your shakedown trip with the radiator repair? Is Frankie back in business?

[DesertDawg]

Almost. Front tyre has delaminated and it needs new boots.

[ossme]

Well, if you have two experts confirming it then good luck with that.

If you are using stock radiator then you should just replace it. It is pretty cheap and mussafah do a bad job at welding them.

[DesertDawg]

Hi Ossme,

It is a big custom made 3 row all metal radiator. It works great, but suffers a constant problem at one joint. This has now been brazed and is sorted.

I hope.

Lower Control Arm Bush Replacement

Inspired by Blackbird I decided to swap out my front axle bushing to make things a bit tighter. Starting with the LCAs

What a state they were in:

Daylight all around the inner location spindle. No wonder my front axle clunks.

Pushing in the new all rubber bush:

Next the UCAs

A neat trick.

But than using the vice like i do
