Guest Ictoan Posted May 13, 2006 Another question for you knowledgeable guys out there. Can I tell which head I have without taking it off? The engine number starts B6D, it has taper seated plugs, is on a 1986 D reg 1.6 Gti first registered on 6/11/86 but it is a rally car so I cannot be 100% certain it is the original engine. It doesn't 'feel' like 115bhp, but that isn't a very accurate way of telling for sure. What should I be looking for? Thanks again, Tim Share this post Link to post Share on other sites
pug_ham 245 3 Cars Posted May 13, 2006 Thats all you can go by without taking the head apart & measuring the valves & camshaft. My old 309 SRi had a B6D 115bhp engine with taper seat spark plugs & that went well. Graham. Share this post Link to post Share on other sites
Guest Ictoan Posted May 13, 2006 Thanks Graham. It looks like the head will have to come off then. Tim Share this post Link to post Share on other sites
Miles 331 1 Cars Posted May 13, 2006 Just check the date stamp on the head, Anything after 04-86 will be the 115bhp version, Don;t forget some 1.6's feel very slow, It's all down to all engines being different. I;ve had one years ago checked it all and was even low milage and not that old at the time and you had a job to keep up with anything Share this post Link to post Share on other sites
pug309twin40s 1 Posted May 13, 2006 also the 105bhp engine doesnt have the oil breather pipe connection on the rocker cover. also as already said some 1.6's feel slower then other 1.6's. my first 1.6 205 didnt feel that fast compared to my old 309 sri that was bl**dy quick Share this post Link to post Share on other sites

Which pretty much contradicts this whole thread! Share this post Link to post Share on other sites
steve@cornwall 100 Posted November 18, 2006 Shouldn't the 105 have hex head bolts,not torx? (unless changed in the last 20 yrs) Share this post Link to post Share on other sites
Miles 331 1 Cars Posted November 18, 2006 The other differance, is when the engine's changed the dash clocks did to flat faced unlike the recessed dials most cars have, Side repeater's add, Different stalks for wiper's etc, Std passenger wing mirror to name a few Share this post Link to post Share on other sites
