Eagle 1679 Report post Posted August 17, 2018 First basic checks do id are make sure no vacuum leaks from split intake boots then check plugs, distrubutor cap and rotor. 1 Quote Share this post Link to post Share on other sites
Jimmyjamese32 4 Report post Posted August 17, 2018 Ok so have confirmed spark to all plugs, leads and distrubutor etc obviously fine, 2nd spark plug in, no 1 is getting absolutely saturated, have cleaned and dryed twice along with rest, I originally narrowed it down to this plug. Are we looking now at the injector? Seal or completely gone causing flooding to the plug equalling the miss Quote Share this post Link to post Share on other sites
hotwire 352 Report post Posted August 17, 2018 More likely a dead plug. If it doesn't light the fire then it will be wet with fuel. 1 1 Quote Share this post Link to post Share on other sites

Olaf 3341 Report post Posted August 17, 2018 did you also check for vacuum leaks and split intake boot as @Eagle suggested? Quote Share this post Link to post Share on other sites
Jimmyjamese32 4 Report post Posted August 18, 2018 Replaced that spark plug today, still instantly missing and checked after covered in oil , we looking at valve cover seal/gasket Quote Share this post Link to post Share on other sites
*Glenn* 855 Report post Posted August 18, 2018 Broken rocker arm or ignition cross fire to earth in distributor cap. Have you also checked compression on that cylinder ? These are just suggestions Quote Share this post Link to post Share on other sites
Jimmyjamese32 4 Report post Posted August 18, 2018 The car has also had a very strong/ loud tapping noise from head, this maybe was a sign? and somethings completely given out now ? Quote Share this post Link to post Share on other sites
*Glenn* 855 Report post Posted August 18, 2018 Get the rocker cover off and have look... not a cheap fix unfortunately 1 Quote Share this post Link to post Share on other sites

Probably been neglected\abused if its broken.If so a replacement head would be the best bet but may not be worth fixing. Quote Share this post Link to post Share on other sites
Jimmyjamese32 4 Report post Posted August 18, 2018 Fixing any issue is worth it for the old girl to me, love the car. Yup I'l remove cover tommrw. It will tell a story for sure Quote Share this post Link to post Share on other sites
Jimmyjamese32 4 Report post Posted August 18, 2018 Narrowing it down to possibly head gasket, obviously blown out allowing oil in spark plug holes, excess oil around front engine were bolts down, looks very recent Quote Share this post Link to post Share on other sites
Eagle 1679 Report post Posted August 18, 2018 Headgasket? Im confused. Are you saying you think the valve cover gasket is leaking into no1 spark plug well\hole causing a misfire?. Did you take the valve cover gasket off? Quote Share this post Link to post Share on other sites
Jimmyjamese32 4 Report post Posted August 19, 2018 .Broken intake side rocker arm. Whoop whoop. Anyone have headbolt order please Quote Share this post Link to post Share on other sites
Eagle 1679 Report post Posted August 19, 2018 When pulling the head you want to get a gasket set like this: https://www.fcpeuro.com/products/bmw-cylinder-head-gasket-set-elring-11129059238 Head bolts: https://www.fcpeuro.com/products/bmw-engine-cylinder-head-bolt-11120621144 Quote Share this post Link to post Share on other sites
B.M.W Ltd 950 Report post Posted August 19, 2018 He will need more than a head set and bolt set to repair this properly Quote Share this post Link to post Share on other sites
Eagle 1679 Report post Posted August 19, 2018 Thats a given but i imagine he would be getting a replacement head, new arms or whatever Quote Share this post Link to post Share on other sites
