Re: Exhaust

For reasons I can't remember, the general advice I seem to think is not to use stainless exhaust studs. I bough these a couple of weeks ago https://www.ebay.co.uk/itm/VW-GOLF-MK1-MK2-MK3-T25-CAMPER-CORRADO-EXHAUST-MANIFOLD-STUDS-NUTS-x-8-A712/221605260320?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p20603...

Re: Exhaust

Some of them don’t look too bad and should clean up with a wire brush and some plus gas. The ones holding on the push rod covers look a bit rough though, to me it looks like a nut with a captive washer put on the wrong way but I may be wrong. It’s quite usual to have a mix of bolts and studs. David...

Re: Exhaust

So your studs should be 12 years old, and the nuts 8 according to the paperwork you have. Might be alright - depends what quality was fitted, and if you have mild steel, stainless or copper flashed nuts (or just balls of rust that look like nuts!) I’d start with a really good inspection of each nut ...

Re: JP Exhaust vs VW Speedshop

Finally got round to ordering a new exhaust - a shiny VW Speedshop one: https://live.staticflickr.com/65535/49781105157_f265817c96_k.jpg Yesterday was a sunny day, so thought I’d have a crack at fitting. First relocate to dead end at the end of the road to avoid Covidiots coughing on me - today’s lu...

Re: Temp gauge sender - linear resistance?

The ideal solution would be to have the temp gauge working normally by establishing if the sender is the problem. I would remove it and heat it up by suspending it in a pan of water and bring it to boiling point. The resistance as you get to boiling point should be around 100 ohms. If it is much le...

Re: Temp gauge sender - linear resistance?

A resistor would have to be placed in series which is not an ideal solution. The resistance of the sender should be around 100 ohms for the gauge to sit left of the LED. Did you lose coolant when you replaced the sender? I lost a fair amount of coolant, but have replaced it and also bled the system...

Temp gauge sender - linear resistance?

New temperature gauge sender fitted to 1.9wbx. Black square plug one identical to the one on there. However, temperature gauge now sits at 3/4 rather than the led. When it gets to fan cutting in it’s right at the hot end. Whilst it’s only an indication it keeps making me nervous when I glance down t...

Re: An Engine Rebuild Thread for Beginners

I hear what you are all saying but this is a beginners thread. a long as valve guides are in spec leave them. valve seats out of spec are not a big issue in my experience. it may not do 100,000 miles like this but most of us do 2000 a year camping and so thay will be fine. Just replace the bad valv...

Re: An Engine Rebuild Thread for Beginners

I think that the bit that won't shine is burnt - poor seal between valve and head lets hot gas and explosion out, burns valve, worse seal, less contact means more heat in valve, more burn and repeat. Slowly valve gets worse until you loose compression. Small crack there is normally fine, just see if...

Re: T25 Engine Opportunity

^^ What he said! You had one running issue, which you fixed. Then you had another issue with the clutch that you have failed to fix. There are limits to what can be wrong - and if I had to guess i would suggest your mechanic may have no idea what he was doing. It should cost you significantly less t...

Re: An Engine Rebuild Thread for Beginners

Good to hear you are back at it!

Personally I would replace all of the valves (or at least the exhaust valves as a minimum).

They have a very hard life and are prone to failure and aren’t that expensive (around £80 all in).

Saves you some cleaning time too!!

Re: noticed a small leak this morning

I received some criticism for this in the past, so feel free to ignore me! I had a similar small weep from a head seal, which I ‘fixed’ by smearing some sealant on the outside of the seal and head. As there is no real pressure behind these weepy type leaks it will hold for a reasonable length of tim...
