John K Posted August 12, 2018 Report Share Posted August 12, 2018 The 987 hadn't been run for 5 days and when I started it this morning I got a tappet (or follower or something, it just sounded like a tappet) tick from the drivers side. As soon as it was warm, I gave it a gentle rev and all went back to normal Its never happened before and the only new parameter was a recent service and new oil. Is the new oil less viscose so ran out of the engine easier..? No idea, just guessing. Don't even know if it has tappets... Link to comment Share on other sites More sharing options...
Menoporsche Posted August 12, 2018 Report Share Posted August 12, 2018 I think if you drive it fully submerged through sheep dip you should cure it of ticks. Link to comment Share on other sites More sharing options...

If it hadn't been run for a while it can take a little while for everything to "settle" - its also apparently not uncommon for a follower to stick and needs a little enthusiasm to get things back to normal. One thing - I was told by an engine builder and I have seen reference to the same in various cars owners manuals - to not "just sit there and let things warm up" - its much better to get things moving and drive reasonably gently until it's warmed up - (I think the boxster manual says below 4000 rpm until it comes up to temp) - the explanation I was given by the builder was that at idle the oil pressure is relatively low -meaning that it doesn't make it all the way to all the "important" bits as well.

As to your second point about not sitting warming it up. I got told exactly the same by the previous owner and that's what I do. It gets driven gently as soon as it starts (I was limiting myself to 3k) but as soon as the temp gauge sits at 80 deg C, it's "cry havoc and let loose the dogs of war..."

Mattman42 Posted August 13, 2018 Report Share Posted August 13, 2018 seen a few references to ticking noise - seems to be the noisy followers and fairly common - you obviously aren't going fast enough if you can hear it Link to comment Share on other sites More sharing options...

SteveEu Posted August 15, 2018 Report Share Posted August 15, 2018 Mine makes a ticking noise when cold on the offside and was told by the mechanic that if you put your ear to the offside grille and it’s coming from there it’s usually the injectors and perfectly normal. Thoughts? Link to comment Share on other sites More sharing options...
John K Posted August 15, 2018 Author Report Share Posted August 15, 2018 I went out this afternoon and the tick was still away. I'm sure what I heard was a sticking something. I might be out for a trundle tonight and will have a little listen at the grill. Makes sense you would hear the injectors on a DFI Link to comment Share on other sites More sharing options...
Lonewolfgjp Posted August 15, 2018 Report Share Posted August 15, 2018 Mine was parked up and on slope for the best part of a week and I had a tick when I moved it. Took for a gentle run up to temperature and it went ? I think the oil must drain out or something but mine seems fine ? Link to comment Share on other sites More sharing options...
banjo1 Posted August 15, 2018 Report Share Posted August 15, 2018 the lifters are hydraulic and the oil can drain over time.nothing to worry about. Link to comment Share on other sites More sharing options...
detail1 Posted August 19, 2018 Report Share Posted August 19, 2018 Mine has been in the bodyshop for a week, noticed a tick noise when first starting up, after a blast round half the M25 all was good. Based upon that I'd say it was normal and things just needed lubricating. Link to comment Share on other sites More sharing options...
mk1max Posted August 21, 2018 Report Share Posted August 21, 2018 Just had a chat with my mechanic this morning and he said something interesting about my 986 (which is ticking too) which probably applies here too. The standard oil used is quite thin; I put Mobil Gulf in it and he was recommending Millers (and a mineral oil as car gets older rather than synthetic) as something that is a bit thicker. This tends to stick to the lifters a bit longer and reduces the ticking - and wear. Obviously if the ticking goes away wear should be less of an issue. Still, thought it was an interesting point as I assumed that when it came to viscosity, 5w-40 oil was 5w-40 oil, but apparently not. Link to comment Share on other sites More sharing options...
