Front crankshaft oilseal sqeak.......
Hi all,
I have a brain teaser and have decided to ask you Amazon die hards. I owned Amazons many years ago and done the obligatory fibre gear change etc and general maintenance but coming up to the present day this one has me wondering. So......I've rebuilt my B18 engine on my latest aquisition and changed the oil seals to neoprene and done all the usual oil pump,shells,rings,bore glaze busting in fact you name I've done it to this engine that has not run for 27 years till I did the business. So...... now last week I primed the oil galleries, got oil in the rocker shaft,left the valve adjustment on the loose side for now,set the timing and fired her up immediately. She ran well and I kept the revs up around a 1000 plus for a few minutes then a sqeak developed,disconnected the water pump and dynamo belt...still had the squeak. Put some oil behind the crank pulley and .....eureka no squeak. So connected w/pump etc and ran it for around 20 mins at around 1500 - 2000 revs to bed in the rings etc and all was fine. BUT trailered it to a show the weekend and moved it a couple of times this week on the workshop yard with intentions of now giving it a running in period and the sqeak is back...so....is it the neoprene seal not getting fed with oil or may be I'm worrying too much or perhaps it's partial front strip out to check my assembly, anyone any ideas it would be much appreciated cos' it's not one I've come across before. |

On assembly, did you lubricate the seal with rubber grease?
Salut! Pookie

Errm no.................!!....and the rebuild was done last year so sounds rather like I have to pop off the pulley.
Is silicon grease a good option too? |

Most engine workshop manuals say engine oil - what's the recommendation in the Volvo manual?
I don't want to cause a panic but removal of the seal and checking the running surfaces of the crank and the seal seems to me to be a good way to start with this problem - pressure loss from a leaking crankshaft seal can cause a fair amount of wear (which would be a shame)

Thanks for the comments gents, I'm sure I used a little engine oil on the crank on reassembly, it's normally rule of thumb to smear these type of parts on assembly.
I've got a suspicion that maybe it's the oil jet spray on the timing gear as it was overlooked when I injected fluids with my airline into the galleries before reassembly.........just to recap the engine runs very sweet and having run it for 20 mins @ 2000 revs with no issues including normal temperature range then I feel nothing serious is iminent accept oilseal failure from timing cover. I think removal of front pulley may give an indication of oil presence in the frontal area would you gents agree? |
