With IHC tractors, oil-moist engine blocks, oil drops underneath the tractor, or oil-contaminated attachments are a well-known issue. Typical causes include crankshaft seals, valve cover gaskets, oil pan gaskets, or pushrod tubes. In particular, shaft seals and rubber gaskets lose their elasticity over the years due to heat and operating hours and no longer provide a proper seal.
With LecWec, you can restore the functionality of these seals directly during operation without opening the engine or carrying out extensive disassembly work.

Depending on the engine series, IHC engines use shaft seals, O-rings, as well as paper and flat gaskets. Polymer-based seals at the crankshaft, camshaft, and auxiliary components in particular lose their plasticizers over time due to aging and thermal stress. They become hard, shrink, and lose their sealing performance. This is exactly where LecWec takes effect during normal operation.
After being added, LecWec circulates through the engine oil and reaches all relevant sealing points within the system. The active formula is absorbed by the polymer seals and helps restore their original properties. The material becomes flexible again and fits tightly against the running surfaces. This closes the typical leakage gaps found at shaft seals and sealing lips.
In practical use, this means that oil loss is significantly reduced or stopped, provided the cause is aged seals. LecWec does not work directly on paper or metal gaskets, but it can restore the sealing performance of the overall system when the main leakage originates from polymer sealing points.
"I have to report positively that the level matches the oil... unbelievable. [...] I wouldn’t have believed that the steering gearbox would be sealed again after just under a week."

"...nothing was leaking anymore!!!
I am truly very satisfied. At first, I did not believe the product would work, but now I am completely convinced and also saved many hundreds of euros!"

Oil leak at the cylinder base gasket
Verified review (Learn more)"I did not believe it at first, but your product is excellent! [...] I ordered just one can and everything is sealed already, even though you recommend 2 cans, meaning 200 ml, for 6 liters of oil. Many thanks!"

Oil leak problems at the oil flange gasket
Verified review (Learn more)"...which made it even more satisfying when, after around 3 weeks, I noticed that the oil loss had gone down to zero – the steering rack was sealed again!! Even now, after 4 months, the reservoir is still at the maximum level."

Oil leak at the steering rack
Verified review (Learn more)"There was always a small puddle of oil collecting underneath the vehicle. I added 100 ml of LecWec to around 4 liters of oil. Since then, I have driven many miles and was surprised to find that there was no more oil on the ground at all."

Leak at the oil pan
Verified review (Learn more)If your IHC engine is leaking oil, this is usually noticeable through an oil film on the engine block, oil drops underneath the tractor, or typical leak points at shafts and housings. In many cases, aged shaft seals or valve cover gaskets are the cause. Instead of dismantling the engine immediately, you can address the issue directly within the system.
Step 1: Check the oil level and identify typical leak points (for example crankshaft, oil pan gasket, or valve cover).
Step 2: Add LecWec directly to the engine oil at a ratio of 3% of the total oil volume.
Step 3: Operate the tractor normally – the additive will circulate throughout the entire oil system.
The polymer seals absorb the active formula, become flexible again, and fit tightly against the sealing surfaces once more. This reduces or stops oil leaks at typical IHC weak points. You avoid unnecessary disassembly and keep the engine operational and properly sealed.
Know the typical IHC leak points
Crankshaft seals, valve cover gaskets, oil pan gaskets, and auxiliary components are among the most common causes. Clean the engine thoroughly and inspect it carefully.
Check the crankcase ventilation
Restricted crankcase ventilation increases pressure inside the engine and can worsen oil leaks. Inspect the system condition.
Inspect sealing surfaces and bolt connections
Loose bolts or uneven sealing surfaces can quickly lead to oil leaks. Check these areas first.
Restore seals in a targeted way
Many IHC engines use shaft seals and rubber seals that harden over time. This is exactly where LecWec can restore sealing performance.
Use LecWec correctly and monitor the results
Dose LecWec at 3% of the oil volume and operate the tractor normally. Monitor the known leak points afterward. In many cases, oil leakage is significantly reduced or completely stopped.
