Jaybo Posted February 24, 2012 Report Share Posted February 24, 2012 Hi all, just got some bad news today about my Lupo S. She had been running lumpy so I got my local Dub tuner to have a look at it and as I suspected it needed the throttle body cleaned and reset, We done this but it didnt make that much difference other that to cure the fault code on vag.com. He reckons that the engine has just had it, due to the 104k miles and prob poor servicing from previous owners and recommended that I get a new engine On a positive note though this may give me an excuse to throw a GTI engine in out of a Golf etc, but I have very little knowledge when it comes to this stuff.Can someone advise me as to what would be the best engine to change to and what parts I will likely need to source and change, ie: gearbox, drive shafts, loom and ecu etc etc.More importantly a rough idea of what I can expect to pay for a swap out like this, bearing in mind I have a friend who will prob do the labour and give me a hand for next to nothing??Cheers Quote Link to comment Share on other sites More sharing options...

I thought the gear box would need changed.Do you know if its a direct fit? I know the engines look pretty similar in size and I'm hoping the mounts all lline up etc.cheers Quote Link to comment Share on other sites More sharing options...

Rich Posted February 24, 2012 Report Share Posted February 24, 2012 It all depends on how much time/money you've got and whether or not you'e done anything like this before.You'll also have to do better than 'running lumpy' to describe your engine as dead.If it hasn't actually gone 'boom' then you're not doing it properly.

Jaybo Posted February 24, 2012 Author Report Share Posted February 24, 2012 (edited) Ok well the car was idleing funny and as I suspected due to having the same issue with my mk4 golf it needed the tb cleaned and reset. We done this and it cleared all the fault codes however, the car was still running a bit off, so we took it a rip down the road to see if that helped but still no change. While out on the run my mechanic recommended that she was losing power and due to the amount of gunk that had built up around the airbox and tb that the piston rings were gone. He recommended that as there is no way of telling what other damage has been caused to the internals of the engine and the mileage I'd be better trying to source one with lower miles, which leads me on to trying to find a gti lump for the wee car Edited February 24, 2012 by Jaybo Quote Link to comment Share on other sites More sharing options...
Defcon5 Posted February 24, 2012 Report Share Posted February 24, 2012 What kind of tuner (I use the word in the loosest sense) writes off an engine because he cant make it run properly?The gunk around the airbox is from the PCV system, not because the piston rings are 'gone'. If they were you would be burning oil like it was going out of fashion.What is actually wrong with it? Quote Link to comment Share on other sites More sharing options...
fatttty Posted February 24, 2012 Report Share Posted February 24, 2012 I'd get a second opinion on your existing engine. Quote Link to comment Share on other sites More sharing options...

If they were you would be burning oil like it was going out of fashion.What is actually wrong with it?Going to have another guy (VW trained) look at it in the morning and see what his diagnosis is. When the car is just ticking over it seems like its loosing power and going to cut out, also when flooring it he reckons his daughters 1.0 is almost as nippy. The previous owner has replaced, plugs, leads and all thoose parts, but at the same time had replaced the stock filter with a K&N type job and removed the standard filter. The guy that looked at the car for me is a mechanic by trade and builds race spec dubs.... he reckons that the previous owner was having the same issues as me (also lied to me about and told me the belts had been done and had put this filter on due to the fact the engine was breathing too hard and blowing gunk back up through the tb, or something along them lines. (He also says that this is a common issue with this type of engine and that they were prob trying to hide the problem) Quote Link to comment Share on other sites More sharing options...
fatttty Posted February 24, 2012 Report Share Posted February 24, 2012 Lack of power and lumpy tends to be coil packs get them checked along with leads, plugs etc Quote Link to comment Share on other sites More sharing options...
Jaybo Posted February 24, 2012 Author Report Share Posted February 24, 2012 As I said above mate all that was done by the previous owner, with receipts to prove Quote Link to comment Share on other sites More sharing options...
Defcon5 Posted February 24, 2012 Report Share Posted February 24, 2012 Genuine ones? What plugs?Clean the EGR Quote Link to comment Share on other sites More sharing options...
Jaybo Posted February 25, 2012 Author Report Share Posted February 25, 2012 Well had the 2nd opinion this morning and he had the same diagnosis as the first guy. He also recommended replacing the engine Quote Link to comment Share on other sites More sharing options...
Jaybo Posted February 28, 2012 Author Report Share Posted February 28, 2012 Was speaking to another guy today, who suggested that the problem may lye with the crankcase breather value. Anyone else had experience of this? Quote Link to comment Share on other sites More sharing options...
Hawkesybaby Posted February 29, 2012 Report Share Posted February 29, 2012 I'd seriously start with ignition for this....Other plugs could have been used as its recommended to change like for like.... leads could be a faulty one in there somewhere? But change the coil pack!!!!!!!! Seriously it'll be worth doing for the price!Also check lambda sensor???You may not need a new engine!

Anyone else had experience of this?A blocked PCV system will cause problems, and I suppose it could increase pressure in the crankcase to the point where it forces oil past the rings.Bit of a change of heart from the mechanic isnt it? We have gone from a thousand pound engine swap to a £50 piece of plastic pipework Quote Link to comment Share on other sites More sharing options...

I got a price from TPS of about 16 quid plus vat for a oem valve, so its worth a shot Quote Link to comment Share on other sites More sharing options...
CasperGTI Posted March 1, 2012 Report Share Posted March 1, 2012 This has happened to a few other members too. Poor running caused by a blocked oil separator valve on the back of the engine.When you replace it, make sure you replace the pipe that comes out of the top of it too, they also get nicely gunned up.John Quote Link to comment Share on other sites More sharing options...
