1.8 sounds like diesel

It could have a slight bent valve. I've known slightly bent valves to straighten on firing, making a tick as it does so.

I'd be very worried if the cam timing was out and the engine run for exactly this reason. The K-series is not a no-impact engine design, meaning that the valves can strike the piston heads if the timing is not correct. If a valve (or valves) have struck the piston face and bent as Nodge suggests, then they risk disintegration and complete engine failure at a later date.

If you have access to an endoscope, you can look down the spark plug holes and see whether there is any evidence of valve/piston contact. Otherwise, it would be sensible to lift the head to inspect carefully. If there has been piston/valve contact, I'd replace all the valves as a matter of course. I'd probably angst over the pistons too, but if low speed impacts and little obvious damage, I'd leave them but worry...

Pinking is premature air/fuel detonation that can occur when there is too much ignition advance, too lean a fuel/air mixture, fuel with too low an octane rating etc.

"pinking' or pre-ignition. When the timing is advanced to much the spark ignites the fuel mix before the piston is at the peak of its travel. It often sounds like a dry rattle when you put your foot down. If you have aligned the cams and crank pulley correctly it's unlikely to get pinking in a K series as the spark is managed by the ECU.

Note: when we set the timing on a K series 1.8 with the cam pulleys and crank pulley aligned correctly, as in the photo above, the pistons are halfway up the bores - this is referred to as the safe position I think. It is not TDC.

That link the Alibro put up above is an excellent reference.

Have you had the head off?

If you can please put a video on here with the motor running so we can hear what's happening.

As above: TDC is not the same as the crank "safe" position used to align the cam pulleys; TDC is approx 25 degrees before "safe". It sounds as though cam timing is now correct, but was quite a way out the first time if you timed everything to TDC.

Yeah maybe I just take top off. But now it has got more annoying fault. Blower works when car is started and works like 3-5 minutes and then shuts no matter what speed it stays dead. But when i turn off ignition and turn on again it starts working again.
And sometimes when I drive it may start working for few minutes.
I already changed blower motor.

That sounds like a dodgy switch.

A heater problem is more annoying than an engine problem.

yeap because i can drive with it even it sound like a diesel engine. but now it rains everyday and here is cold. can't see through windows

...and presumably in a number of weeks that condensation on the inside of the window will be ice.

It is a right pain having to de-ice both sides of the windscreen... and then stop do do it all again 50m after leaving home!

That's why I only buy cars with heated front screens these days. It saves all that faffing about with scrapers and sprays.

Yeap, but I found fault while I was changing switch. Some cable what should have come to switch wen't webasto and webastos relay was oxygenated. I cutted wires and connected them.

The 1.8 has a Webasto FBH? I didn't know LR fitted the FBH to the petrol FL1.

It wasn't original installation, someone in finland just decided to install it.

Sensible move. The FBH in my TD4 is very useful in the winter. It's so nice get into a warm car, first thing in the morning.
