Which Engine.... Car Driving me nutts
Back to my woes with this bloody locost. Looks like there's something completely wrong with my locost.
It's got some serious back pressure in the thing.
I should get through the SVA tomorrow (4th attempt) and will then register it with the current engine fitted.
Now here's my dilemma. I don't really want to throw good money after bad sorting the Pinto. I've already thrown some good money at
it and now it's got this pressure problem. There's obviously something wrong with the bores / wear that I didn't spot before.
So... with a budget of about £ 500 quid what should I do? Remembering that I've got a 5 speed type 9 fitted.
I want the car to be as quick as possible and scare me. With that sort of budget has anyone got any ideas?

Tricky, but thinking aloud here!!!
£500 will completely recon the pinto, and net you 135hp into the bargain, which won't be slow but won't scare you (unless you're a
big wuss )
It will also, if you are unbelieveably careful, stick a Zetec 2.0 or possibly even a Vauxhall XE in there, but funds will be extremely tight. The
Zetec would be the cheaper option of the 2, but either will rely on you either Megasquirt fuel injecting via bike throttle bodies and homemade
manifold, or using s/h webers and megajolt ignition.
Alternatively, for that sort of money, you could go the route that Northy on here has done and fit a vauxhall 2.0 8v engine, which is 130hp as std (if
you get an sri cav one) and these engines are absolutely bulletproof and parts are dirt cheap. The expensive bit is the bellhousing (£170) to connect
to the type 9 box.
To be honest, if you have a pinto now, the best best is probably, much as I don't like to say it, to get the bottom end rebuilt, port the head,
put a road rally cam in it and use it like that

Vince,
In another post didn't you say you already had the 40's for the Pinto?
In which case I would have thought that you could do a pretty reasonable Zetec for £500.
The exhaust would be the most expensive part but you could always weld up your own if funds don't allow a sexy MK one!
At the end of the day a new Pinto block isn't going to cost you much if you just swapped the block!
HTH,
James

Thanks for the replies guys.
The pinto that is currently in the car has had some money thrown at it as follows.
Porting the head (myself as per a book I bought)
Fast road Cam and followers.
Twin webbers (40s) and obviously manifold to suit.
Shortened sump and oil pickup.
Lightened flywheel (cost me 4 cans of Stella, specs to book mentioned above)
The thing that's confusing me is that the car was very low mileage. (donor) and the engine had still got the cross hatch honeing marks in the
bores. There was no ridge at the top of the bores where the bores had worn.
It's now got me thinking if I've got a blown head gasket. Or mabye I've got something wrong with the head after porting it?

Maybe it just wants the bores honing again and a fresh set of rings, how have you got the breather system set up?.I have a catch tank on my car and it
was blowing out oil until iI increased the bore of the breather hose , now ok.
It wouldnt be to expensive to change to a zetec using your existing webers, if you get an 1800 engine then the flywheel waterpump etc wont need
changing.

I've got a catch tank myself. It's up high though and is fastened to the side of the battery.
The bore of the pipe is 19mm so should be plenty big enough.
The cylinder head gasket was *issing out water / oil from the side when it was on the rolling road and being given some real greif yesterday.

Sorry I seem to be coming in late on this thread, but it seems to me that the 'back pressure' should be investigated before doing anything
drastic.
I have had problems with my pinto not keeping oil in (at one point if I took the dipstick out with the engine running the windsreen got covered with
oil!!) but at the end of the day it turned out to be poor breathing.
How have you arranged your breathing system?
I have ended up with a straight through connection from the crankcase where the flame trap normally goes and a connection from a vented filler cap
both of which vent into a 1 litre catch tank with a K&N breather filter to the atmosphere.
The catch tank has a drain straight into the sump so I don't have to keep emptying it.
This system works for me, although at one point - the point where the dipstick tube sprayed my windscreen with oil, I was ready to bin the engine
because it didn't seem to be working. Turned out the breather filter had become clogged - a new one sorted it and it has been fine ever
since.
Vince, I am only in Harrogate and I would be happy to drop by to have a look to see if I can spot anything if it helps.
Cheers
Mark

Yeah. I'll get the SVA out of the way and then have a look at it. At least that will be one "worry" out of the way.

Just a thought - ignoring the head gasket for the moment (although it ain't going to help!) - what oil did you use when you rebuilt the engine?
Old-style engines such as my x-flow and your Pinto DON'T like modern synthetics during the running-in period; the rings will never get settled
into the bores and you'll have blow-by for the rest of the engine's life. I was instructed to use ordinary general-purpose oil (in my
case, Duckhams) for the first 500 miles or so, then change to synthetics if I wanted to.
If the rings haven't settled in then a re-hone may well bring it back to a state where you can try again.
Disclaimer - other people may say something totally different - but I have done as I was told!
rgds,
David

I'm pretty sure I used Castrol GTX liquid engineering.
I've got to get the head off to change the gasket so may re-hone... new rings if there's no wear in the bores.

If the cylinders don't look too bad, and you don't think they need a rehone, but you think the rings still aren't sealing as well as
they can be, you could try the "comet" fix.
Before I explain it though, it should be known its a little..."backyard engineering" although many dealerships do it when they get new
cars.
Over here in the states, they sell abrasive powdered cleaning products (for the bath, toilet, kitchen etc.) that you mix with water. The 2 big
brands are "comet" and "ajax" I'm sure there is something similar in the uk, but i'll ask my gran to be sure.
To do it, run the engine up to temp. Take your air filer off, or any kind of induction pipe. Sprikle the powdered comet into the intake, so it
get's sucked into the engine. Use about 1 tablespoon per cylinder. Since it's abrasive (but only mildly mildly so), it helps the rings
seal a lot better.
After I rebuilt the engine in my mitsubishi eclipse (shares the same engine as the EVO), I was having ring sealing problems. An "old
timer" shared this technique with me, and it worked.
Like I said, it isn't exactly science, but it's worth a try.

sounds awful, but I've seen it done and it does work!
However, the head needs to come off anyway for the gasket to be checked out, and it's not a big job on the pinto, so might as well do it that
way.
