98 1.8td 'Squelching' noise when revving engine. - damian1978
Hello everyone, I'm new to this site and I've recently bought a '98 Mondeo 1.8TD, it's got 120K on the clock and seems to run well - most of the time. I've just noticed that when going up a nearby steep hill and having dropped to 2nd gear on full throttle, I get some 'stuttering' as if I'm running out of fuel - although I have half a tank. It doesn't last long, although it's done it on a couple of occasions on the same hill, under the same conditions.

I've also noticed that when idling and if I blip the throttle, I hear what I can only describe as a'squelching' sound which appears to be coming from the passenger front footwell.

Finally, I've spotted a small in line fuel filter (looks obviously not a standard fitment) in the fuel pipe to the injection pump.

Could these three things be related do you think? Is there anything throttle related near the passenger footwell that could cause the noise I'm hearing? What's the most likely cause for the apparant fuel starvation problemm?

Sorry for the barrage of questions - I'd just like to nip this in the bud as quick as poss!

Thanks, Damian.

fuel starvation is likely from the aftermarket filter being a bit clogged up..i would do away with it and fit a new filter in the proper filter housing on the car....the squelching sound is likely to be air in the heater matrix as its proberbly got a pin hole water leak also causing air into the system..does the front windows mist up slightly??
