My JH (16371, door date 03 May 1974) has the black paint on the headlight cowls and I believe it to be original.  The paint is noticeably ...   12-13-2005 02:56 pm

OOH! Shiny! ...   12-12-2005 03:34 pm

Check out Mitch Ware's postings on the JHP photo site at http://jhppg.com/gallery/album27 as well as his JH website.  Also, do recall that the mounts on the front ...   12-02-2005 10:30 pm

What I used on my car was a ribbed stair tread runner, made from a rubber-like material that was found by test to resist gasoline and other ...   12-01-2005 05:24 am

John, The obvious ways of doing the job are to torque the shock bolt before securing the bracket to the lower arm, or, once the bracket is ...   11-26-2005 02:48 pm

I use a 2-jaw puller to get my steering wheel off.  And this is after the splines have been lubricated with anti-sieze compound. What sort of steering ...   11-21-2005 11:20 pm

Came across what appears to be an attempt to acquire eBay user names and passwords for some nefarious purpose.  I sent the email below to the eBay ...   11-21-2005 04:25 pm

Hi, there.  I can't answer all of your questions, but I can comment on some of them. "Are the moderatly fast stock w/ the 907?" Top speed ...   11-21-2005 02:23 pm

If you can't get the arm loose fairly easily, use a Sawz-all or equivalent to cut through the bolt (and bushing ends) between each side of the arm and ...   11-20-2005 06:47 am

Ed's fuel pump looks like the typical Facet / Purolator unit sold by Delta and many other sources.  The one in my car has been ...   11-20-2005 05:54 am

By request, I've posted a couple of photos showing precisely where my car's side mirrors are located.  I don't know if the mirrors were installed ...   11-18-2005 11:06 pm

John, From the lack of response to your question, I think it's fairly safe to presume that nobody has an answer to it as yet. Judging from pictures ...   11-04-2005 03:08 pm

So... if I understand you correctly, you're saying that if I have a pulley with, for example, the markings 'IN 110' and 'EX110' actually cast ...   11-03-2005 02:05 pm

Andy, Welcome, or welcome back, as you prefer.  The phrase 'old and dumb' hardly seems applicable to someone who's sufficiently 'experienced and wise' to buy a JH.   :^} Vacuum Switch. Used only on cars ...   11-02-2005 06:23 pm

Wow. The data in TDA.pdf is an enormously valuable supplement to the JH shop manual -- the ignition timing and cam timing areas, in particular, caught my attention in a brief and ...   11-02-2005 02:46 pm

Unfortunately, the escutcheon sits in a groove in the wheel, and as far as I know, the only way to remove or reinstall the thing is to ...   11-01-2005 07:57 pm

The word 'electronic' is frequently used to justify a large price multiplier by suggesting to the consumer that an item has the reliability of solid-state (transistorized, etc.) ...   10-29-2005 04:35 pm

Turn signals and Hazard lights use the same bulbs but different flashers.  There's also an inlne fuse for the Hazard lights, under the dash on ...   10-28-2005 10:55 pm

I don't know of any published studies for any car using a 907 engine, but there are a few reliable articles (and a lot of hype, ...   10-28-2005 10:30 pm

With good valves and properly seated rings you should see 125-130 psi in each cylinder (at sea level -- 10% less at an altitude of 4000 ...   10-28-2005 03:32 pm

All JHs, and early Lotus cars with the 907 engine, originally came with the A907E0311Y head casting.  At some time after the JH ceased production, Lotus changed the ...   10-25-2005 03:57 pm

Haven't noticed that sort of hose change in my car, either with the old hose or its replacment.  Both were the Gates hoses that Delta provides, ...   10-17-2005 10:23 pm

My car has a Delco unit, and I've never observed the behavior of a Lucas alternator, so my comments apply only to the former.  I would ...   10-16-2005 03:50 pm

Jim Medland is correct in that most of these hoses work just fine.  However, nobody's quality control is perfect, and defective parts do occasionally get made and sold. These ...   10-16-2005 12:52 am

Don't know how Holden did things.  The way I described is the simplest safe approach.  If you don't trust your switches to handle the current needed ...   10-14-2005 05:55 pm

Congratulations on joining the JH family.  Despite its reputation, a JH is actually about as reliable as any other car of its era, provided that the owner ...   10-14-2005 05:10 pm

Dan, Not sure I agree with your comment, as I've noticed several distinct differences between the typical British person who happens to own a Jensen, and the typical British ...   10-14-2005 02:52 pm

The overdrive solenoid should work off +12 volts.  Ideally you would use two switches to control it: one on the dash or shift knob, with ...   10-14-2005 02:28 pm

"... a really interesting spat of revving up and down between 0 and 2500-3000 rpm for a minute or two." This sounds like water in the ...   10-14-2005 12:06 am

Dan, A bit lumpy is normal -- the stock cams aren't all that high lift but the duration is 272° seat to seat, which by most standards ...   10-13-2005 07:43 pm

Ed, Good cars, and good people, are worth maintaining.  Looks like you've been fortunate enough to have both! ...   10-13-2005 06:26 pm

It's my understanding that the various timing changes were the factory's response to the changes in emissions specs (primarily in the US) for the 1973, 1974, and 1975 ...   10-13-2005 03:37 pm

Steve, Whether you have points or a Pertronix, you still need to connect them to the coil or to the ignition control box, as appropriate.  With points this is usually done by ...   10-13-2005 01:04 am

While I wouldn't apply the word 'screwy' to the JH wiring -- which is actually very logical and sensible once you understand what they were ...   10-12-2005 02:12 pm

As you note, this is probably an electrical problem.  In the whole car, about the only things temperature dependent are the sensor for the temp ...   10-11-2005 05:22 pm
