Hi there:

I have a 2005 987 Bosxter, with 55000 kms. I bought it with 49000 kms a couple of months ago.I've been experiencening ticking noise coming from the engine since the first day. Sometimes louder, sometimes softer.

After a lot of reserach, I have found it could be mainly because of the following reasons:

1- Loosen sparks
2- Broken exhaust
3- Bore Scoring
4- Inyectors
5- Lifters

Reasons 1 and 2 are pretty easy to check. Both ok in my case.
Reasons 3 and 4 you need an stethoscope. Pretty cheap to get in Amazon.
Don't really sure how to diagnostic reason 5.

After checking with the stethoscope, I'm pretty sure that my issue is coming from Inyectors. Couldn't really hear anything strange in the cylinders, but noise is quite noticible from the fuel collection rail:

So I'm thinking of changing them. My problem comes when selecting the inyector. The difference in price is incredible (50 € BOSCH Vs 160 € OEM each one).

Has anyone tried Bosch Inyectors?, any issue?

Thanks you for your help.
